When you push a box with 20 N of force, what force does the box apply back on you?
What happens to the boat when its weight is greater than the buoyant force?
What happens to the boat when its weight is less than the buoyant force?
What happens to the boat when its weight is equal to the buoyant force?
Answer:
1. and 2. If the buoyant force is greater than the object's weight, the object rises to the surface and floats. If the buoyant force is less than the object's weight, the object sinks. If the buoyant force equals the object's weight, the object can remain suspended at its present depth.
3. When the buoyant force equals one ton, it will sink no further. When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation” where a floating object displaces a weight of fluid equal to its own weight.

can be concluded that in the first 6 seconds, the car is -
Answer:
Accelerating
Explanation:
A horizontal force of 20 N is applied to the object. Will the force applied make the object move?
It depends on two factors: The direction of application of force and the coefficient of friction, [tex]\mu[/tex], between the object and the surface on which the object is placed.
If the direction of application of force is vertically downwards, then the object will not move for any value of [tex]\mu[/tex].
If the coefficient of friction is zero, [tex]\mu=0[/tex], then any value of force that is not in a vertically downward direction, the object will move.
If the direction of application of force is not vertically downwards, then it depends on the value of frictional force.
Jim and Bob send a car careening off a cliff. The car has a velocity of 16 m/s when it went off the cliff and it lands 35 m from the base of the cliff. How long was the car in the air? How high is the cliff?
Answer:
The time spent in air by the car is 2.19 s
The height of the cliff is 58.5 m
Explanation:
Given;
initial velocity of the car, u = 16 m/s
horizontal distance traveled, R = 35 m
The horizontal distance or range of a projectile is given as;
R = vt
where;
t is the time spent in air by the projectile
t = R/v
t = 35 / 16
t = 2.19 s
The height of the cliff is given as;
h = ut + ¹/₂gt²
h = (16 x 2.19) + ¹/₂(9.8)(2.19)²
h = 58.5 m

why does a thrown football have both potential and kinetic energy?what is the combined energy called?
i will give brainliest to who ever answers this question in a paraghraph
Answer:
The thrown football has Potential or stored Energy, PE, by virtue of its position in the air and the ability for it to fall by itself. The thrown football also has Kinetic Energy, KE, given that the ball is in motion and requires an equal and opposite amount of energy to stop it. Both the PE and the KE are forms of Mechanical Energy, ME and the Mechanical Energy of the football is equal to the sum of its Potential and Kinetic Energy. That is ME = PE + KE
Explanation:
Potential energy, PE, is the energy that is the held or stored energy of a body such that the body is able to do work without the addition of energy from an external source
A thrown football that has an elevation or height above the floor level has the capacity to come back down and bounce on the floor without the presence of assistance at the topmost height of the football. Therefore, the thrown football has potential energy, given to it by the thrower
Kinetic Energy, KE, is the energy possessed by a moving that comes from the motion of the object
Given that the thrown football is in motion, it posses kinetic energy
Therefore, the thrown football possesses both potential energy and kinetic energy which are forms of mechanical energy ME
The combined energy of the football is therefore called the Mechanical Energy ME of the ball which is the sum of the potential and kinetic energies of the football, given as follows;
The Mechanical Energy of the football = The Potential Energy of the football + The Kinetic Energy of the football
∴ ME = PE + KE

A sled is moving down a steep hill. The mass of the sled is 50 kg and the net force acting on it is 20 N. What must be done to find the acceleration of the sled?
You need to first measure the angle of descent, i.e. the angle the hill makes with the ground. Then identify the forces acting on the sled, split them up into horizontal and vertical components, or into components that are parallel and perpendicular to the hill, and use Newton's second law to determine the components of the sled's acceleration vector.
There are at least 2 forces acting on the sled:
• its weight, pointing downward with magnitude W = m g
• the normal force, pointing perpendicular to the hill and away from the ground with mag. N
The question doesn't specify, but there might also be friction to consider, indicated in the attachment by the vector F pointing parallel to the slope of the hill and opposing the direction of the sled's motion with mag. F.
Splitting up the forces into parallel/perpendicular components is less work. By Newton's second law, the net force (denoted with ∑ or "sigma" here) in a particular direction is equal to the mass of the sled times its acceleration in that direction:
∑ (//) = W (//) = m a (//)
∑ (⟂) = W (⟂) + N = m a (⟂)
where, for instance, W (//) denotes the component of the sled's weight in the direction parallel to the hill, while a (⟂) denotes the component of the sled's acceleration perpendicular to the hill. If there is friction, you need to add -F to the first equation.
If the hill makes an angle of θ with flat ground, then W makes the same angle with the hill so that
W (//) = -m g sin(θ)
W (⟂) = -m g cos(θ)
So we have
-m g sin(θ) = m a (//) → a (//) = -g sin(θ)
-m g cos(θ) + N = m a (⟂) → a (⟂) = 0
where the last equality follows from the fact that the normal force exactly opposes the perpendicular component of the weight. This is because the sled is moving along the slope of the hill, and not into the air or into the ground.
Then the acceleration vector is
a = a (//)
with magnitude
||a|| = a = g sin(θ).
Answer:
To find the acceleration, you do 20N/50kg = 0.4 m/s^2
Explanation:
example: a = F/m = 10/2 = 5 m/s2

If an airplane with a mass of 4,536 kg has gravitational potential energy of 1000 kilojoules, what is its height?
Answer:
The height is 22,472.84 m
Explanation:
Gravitational potential energy is the type of energy that is stored in the gravitational field. In other words, the gravitational potential energy as the energy that a body possesses due to the fact of being under the action of gravity, that is, the energy associated with an object subjected to force, weight, and weight is called gravitational potential energy. that is at a certain height with respect to a reference level.
The greater the weight of a body, the greater the gravitational potential energy and, considering the effect of this variable together with that of the height h at which the object is, the gravitational potential energy is:
Ep = m*g*h
In this case:
Ep= 1,000 kJ= 1,000,000 J (being 1 kJ=1,000 J)m=4.536 kgg= 9.81 [tex]\frac{m}{s^{2} }[/tex]h=?Replacing:
1,000,000 J=4.536 kg* 9.81 [tex]\frac{m}{s^{2} }[/tex] *h
Solving:
[tex]h=\frac{1,000,000 J}{4.536 kg*9.81\frac{m}{s^{2} } }[/tex]
h= 22,472.84 m
The height is 22,472.84 m
Which statement about natural resources is true?
A. All societies have the same natural resources available to them.
B. Societies have found alternatives for them, so natural resources
have lost all their importance.
C. While all societies use natural resources, they do not use them in
the same way
D. Some societies find natural resources important, while others find no need for them.
Answer:
C. While all societies use natural resources, they do not use them in
the same way
Explanation:
Natural resources are endowments by nature in a particular place. Different regions of the world have either similar or varied types of resources.
Therefore, with cultural influences and climate, these resources are put into different forms of usage.
All societies does not use natural resources the same way. There are certain influences most especially based on needs that determines what a particular resource can be used for or not. Although synthetic materials serves as alternatives to natural resources, the cost and energy required to produce them is most times discouraging.ANSWER QUICK!!
