A. The total kinetic energy cannot be determined.
B. The total kinetic energy decreases.
C. The total kinetic energy increases.
D. The total kinetic energy remains the same.
Answers
When the mass of the cannon increases and the energy of the blast remains the same, the total kinetic energy remains the same.
Kinetic energy refers to the form of energy that an object possesses due to its motion. It is known as the work that's required to move a body.
It should be noted that when there is an increase in the mass of the cannon while the energy of the blast remains the same, then in such a situation, the total kinetic energy will remain the same.

A. 0.36 m/s2 to the left
B. 1.46 m/s2 to the left
C. 0.36 m/s2 to the right
D. 1.47m/s2 to the right
Answers
Answer:
Option A. 0.36 m/s to the left
Explanation:
From the question given above, the following data were obtained:
Force resistance (Fᵣ) = 55.2 N
Applied force (Fₐ) = 31.8 N
Mass (m) = 65.2 kg.
Acceleration (a) =?
Next, we shall determine the net force acting on the skateboarder. This can be obtained as illustrated below:
Force resistance (Fᵣ) = 55.2 N
Applied force (Fₐ) = 31.8 N
Net force (Fₙ) =?
Fₙ = Fᵣ – Fₐ
Fₙ = 55.2 – 31.8
Fₙ = 23.4 N to the left
Finally, we shall determine the acceleration of the skateboarder. This can be obtained as follow:
Mass (m) = 65.2 kg.
Net force (Fₙ) = 23.4 N to the left
Acceleration (a) =?
F = ma
23.4 = 65.2 × a
Divide both side by 65.2
a = 23.4 / 65.2
a = 0.36 m/s
Since the net force acting on the skateboarder is to the left. Therefore, the acceleration of the stakeholder will also be towards the left (i.e 0.36 m/s to the left)
Answer:
A. 0.36 m/s to the left

The air in a tire pump has a volume of 1.50L at a temperature of 5◦C. If the temperature is increased to 30◦C and the pressure remains constant, what is the new volume? Hurry Please!
Answers
Answer:
1.6L
Explanation:
Given parameters:
Initial volume = 1.5L
Initial temperature = 5°C = 5 + 273 = 278K
Final temperature = 30°C = 30 + 273 = 303K
Unknown:
Final or new volume = ?
Solution;
Since pressure is constant, we simply apply Charles's law to solve this problem.
Using the expression below,
[tex]\frac{V_{1} }{T_{1} }[/tex] = [tex]\frac{V_{2} }{T_{2} }[/tex]
V and T are volume and temperature
1 and 2 are initial and final states
Insert the parameters and solve;
[tex]\frac{1.5}{278}[/tex] = [tex]\frac{V_{2} }{303}[/tex]
278V₂ = 1.5 x 303
V₂ = 1.6L
Which of these pairs of quantities is used to describe the transfer of energy to or from a substance? A. heat and work B. heat and kinetic energy C. work and potential energy D. potential energy and kinetic energy
Answers
Answer:
B. heat and kinetic energy
Explanation:
Heat is a form of energy that flows with respect to temperature difference. Thus, heat energy would flow from an object with higher temperature to that at lower temperature. It generally cascades from a high temperature body to lower temperature body through a medium or when in contact.
Kinetic energy is the energy that is inherent in a moving object. Thus, it can be converted to other forms or transferred between objects. Example, a moving object can transfer part of its kinetic energy to an object at rest on collision. This may cause the motion of the initial stationary object.
Therefore, heat and kinetic energy can be used to describe transfer of energy to or from a substance.

The Equivalence Principle of Gravity
Explanation:
The fact that objects fall to earth at the same speed is called the Equivalence Principle of Gravity.
What is the Equivalence Principle of Gravity?According to the Equivalence Principle of Gravity, all things fall at the same rate when there is little to no air resistance. The value of the acceleration caused by gravity is demonstrated by the force of gravity equation to be a constant that is independent of the mass of the item.
According to Einstein's equivalence principle, it is unnecessary to distinguish between gravitational and inertial forces because they are comparable in nature.
The inertia force acts in the opposite direction of an object's accelerating force.As a result, the Einstein equivalence principle can be expressed as "the effects of gravity are exactly identical to the effects of acceleration."Therefore, the Equivalence Principle of Gravity states that all objects descend to Earth at the same rate.

John travels 250 miles North, but then 105 miles South to pick up a friend. What is his total distance and displacement? 355 miles total distance and 355 miles South displacement 145 miles total distance and 355 miles North displacement 145 miles total distance and 145 miles South displacement 355 miles total distance and 145 miles North displacement
Answers
Answer:
The displacement is 145 m in the north direction and the distance is 355 miles.
Explanation:
The distance traveled by a mobile is the length of its trajectory and it is a scalar quantity. In other words, distance refers to the space traveled by an object during its movement. It is calculated as the sum of all the distances traveled. In this case:
250 miles + 105 miles= 355 miles
On the other hand, displacement refers to the distance from a start position to an end position regardless of the travel. That is, like distance, displacement is a measure of length. Instead, the displacement is a vector quantity that depends on the direction, so it is described from the magnitude and the direction.
Mathematically, the displacement d is calculated as:
d = df - di
where df is the final position and di is the initial position of the object.
In this case:
displacement= 250 miles - 105 miles= 145 miles
Since the north distance is greater than the south distance, then the displacement is 145 m in the north direction and the distance is 355 miles.

What will the final velocity of a 5.0 g bullet starting from rest, if a net force of 45 N is applied over a distance of 0.80 m?
Answers
Answer:
The final velocity of the bullet is approximately 3.795 m/s
Explanation:
The given parameters are;
The mass of the bullet, m = 5.0 g
The force applied to the bullet, F = 45 N
The distance over which the force is applied, d = 0.80 m
Therefore, we have;
The final kinetic energy of the bullet = = 1/2 × m × v² = The work done on the bullet by the 45 N force = F × d
Where;
v = The final velocity of the bullet
By substitution, we get;
The final kinetic energy of the bullet = 1/2 × 5.0 × v² = 45 × 0.8
1/2 × 5.0 × v² = 45 × 0.8
v² = (45 × 0.8)/(1/2 × 5.0) = 14.4
v = √14.4 ≈ 3.795
The final velocity of the bullet = v ≈ 3.795 m/s

A softball has a mass of 0.18 kg. What is the gravitational force on Earth due to the ball, and what is the Earth's resulting acceleration? Earth's mass is 6.0 x 1024 kg.
Answers
Answer:F=1.7802
Explanation:
Since we've been given the mass to be .18kg,we are asked to find the Force of which the formulae is
F=ma where f-force,m-mass and a-acceleration due to gravity
So we can just substitute
F-?.m=.18 and a9.89
F=.18×9.89
F=1.7802N
The gravitational force on Earth due to the ball will be 1..769 N . While the Earth's resulting acceleration will be 2.9 ×10²³ m/sec².
What is gravitational force?Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force
The given data in the problem is;
m is the mass of ball=0.18 kg
F is the gravitational force=?
m is the mass of earth= 6.0 x 1024 kg.
r is the radius of earth = 6.3781×106 m
G is the universal gravitational constant= 6.67408×10-11 Nm/kg2
The gravitational force is given by;
[tex]\rm F_G=\frac{ G m_1m_2}{r^2} \\\\ \rm F_G=\frac{ 6.67 \times 10^{-11} 0.18 \times 6.0 \times 10^{24}}{6.3781\times 10^6)2}[/tex]
[tex]\rm F_G= 1.769 N[/tex]
Hence the gravitational force on Earth due to the ball will be 1..769 N.
The force is given as the product of mass and acceleration. So that the value of acceleration is found by;
[tex]\rm a= \frac{F}{m} \\\\ \rm a= \frac{1.769}{6.0 \times 10^{24}}[/tex]

C. the north pole of one magnet is near the South pole of the other magnet.
D. The north pole of one magnet is far away from the South pole of the other magnet.
Answers
Answer:
C
Explanation:
Opposites attract, the north pole of one of the magnet is attracted to the south pole of the other magnet. Two north or south poles will repel away from each other.
The north pole of one magnet is near the South pole of the other magnet.
The ends of a magnet are called its poles. One end is called the north pole, the other is called the south pole. If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other. This is called attraction.
What is magnet ?"A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets."
