Answer:

Matter

Explanation:

Atlantic Ocean (salt water)

Answer:

A force has both Direction and Motion.

Explanation:

For example, when finding acceleration you take the time and divided it by distance. If the thing you are measuring is going in the positive direction, the acceleration will be positive and if it is going in the negative direction the acceleration will be negative.

Magnitude and Direction

Explanation:

Force is a Vector Quantity

As learned in an earlier unit, a vector quantity is a quantity that has both magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the direction.

Answer:

si unit of resistance is Ohm

Answer:

60m/s

Explanation:

Given parameters:

Acceleration  = 2m/s²

Time  = 30s

Unknown:

Change in velocity  = ?

Solution:

Acceleration is the rate of change of velocity with time.

Mathematically;

         Acceleration  = [tex]\frac{Change in velocity }{Time }[/tex]

Now,

 Change in velocity  = Acceleration x time

So,

  input the parameters and solve;

 Change in velocity  = 2 x 30  = 60m/s

Explanation:

The amount of work done to move an electron from the positive plate to the negative plate is :  7.2 * [tex]10^{-19}[/tex] J

Step 1: Given data

magnitude of two parallel plate ( E ) = 180 N/C

Distance between plates ( d ) = 2.5 cm

magnitude of charge on electron  ( e ) = [tex]1.602 * 10^{-19}[/tex]  C

Step 2 :  determine the work done

Work done = qV = еEd

                           = [tex]1.602 * 10^{-19}[/tex]  *  180 * 2.5

                           = 720 * [tex]10^{-22}[/tex] J  ≈   7.2 * [tex]10^{-19}[/tex] J

Hence the amount of work done to move an electron from the positive plate to the negative plate  =  7.2 * [tex]10^{-19}[/tex] J

Answer:

TRUE

Explanation:

When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. The transformation happens when the magnetic field produced by the current causes the wire to move.

The electric force is small in comparison because charges are VERY small but the

gravitational force has to do with the mass of the Earth and Moon.

Answer: Wind follows a pattern because the Earth is spinning in one motion. If we were spinning in one way then another we would have one day go by then the spinning cycle would change and we would have to go through that day all over again, it would not be logical because then we would be in the same season as well, we would be in one season for the rest of our lives until we died.

Answer:

Explanation:

Factors that affect the moment of a force are;

The magnitude of force applied is directly proportional to the moment of force in that for a perpendicular distance d, increased in force applied will result to a higher moment of force. When the perpendicular distance from the pivot is decreased while the force applied remains constant, the moment of force decreases.

Answer:

105 g.m/s

Explanation:

The law of conservation of momemtum states that initial momemtum is equal to final momentum.

initial momentum of orange ball = 165 g.m/s

initial momentum of green ball = 0 g.m/s

final momentum of orange ball = 60 g.m/s

final momentum of green ball = x

165+0=60+x

⇒x = 165-60= 105 g.m/s

the momentum of the green ball right after the collision =105 g.m/s

Answer:

The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases. 

Answer:

Explanation:

Both objects are not moving potential energy means no movement no energy and both objects never move

Answer:

Thus, each atom or ion must contain 16 protons. We are told that the ion also has 14 neutrons, meaning the mass number of the ion is 16 + 14 = 30 Because the ion has 16 protons and 19 electrons, its net charge is -3.

Answer:

The relative velocity of the motorcycle to a passenger in the car is 30 km/h

Explanation:

The question relates to the principle of relative velocity and reference frames

The given parameters are;

The velocity of the motorcycle, v₁ = 120 km/h

The velocity of the car, v₂ = 90 km/h

The relative velocity of an object X with regards to another object Y is the velocity the object X will seem to be moving with to an observer in the rest frame of object Y written as [tex]\underset{v}{\rightarrow}_{X|Y}[/tex] = [tex]\underset{v}{\rightarrow}_{X}[/tex] - [tex]\underset{v}{\rightarrow}_{Y}[/tex]

Therefore, the relative velocity of the motorcycle to the car is [tex]v_{1|2}[/tex] = v₁ -  v₂, which give;

[tex]v_{1|2}[/tex]  = 120 km/h - 90 km/h = 30 km/h

The relative velocity of the motorcycle to a passenger in the car = 30 km/h.

Explanation:

Answer: 2490 J

Explanation:

The formula to calculate kinetic energy is 1/2mv² where,

m = mass = 62.4

v = velocity = 8.94

Kinetic energy = 1/2mv²

= 1/2 × 62.4 × 8.94²

= 1/2 × 62.4 × 79.9236

= 2493.6J

Answer:

unperscriebed drugs can e harmful to your body

Explanation:

Answer:

D. Newton's second law

Explanation:

Newton's second law of motion states that force of an object is a product of its mass and its acceleration.

Mathematically, F= ma where  m is mass and a is acceleration

So from the statement above : The acceleration of an object is proportional to the force applied to it and  inversely proportional to its mass , it can be seen from the formula variation as;

F= ma -----making a the subject of the formula

a= F/ m

a= 1/m * F --------- a  is inversely related to m  as you can see from 1/m but directly related to F  hence;

Increase in mass with the same force applied causes the body to accelerate slower where as when force increases, the body accelerates faster.
