The orange exerts a gravitational force on the apple, which can be calculated using the formula for gravitational force. The apple exerts an equal and opposite gravitational force on the orange.
(a) The orange exerts a gravitational force on the apple. The magnitude of this force can be calculated using the formula for gravitational force: F = G * (m1 * m2) / r^2, where G is the gravitational constant (approximately 6.67430 x 10^-11 N*m^2/kg^2), m1 and m2 are the masses of the two objects, and r is the distance between their centers of mass. Plugging in the values, we have F = (6.67430 x 10^-11 N*m^2/kg^2) * (0.12 kg * 0.20 kg) / (0.75 m)^2. Solving this equation gives us the magnitude of the force of gravity between the orange and apple.
(b) The apple exerts an equal and opposite gravitational force on the orange, as described by Newton's third law of motion. This means that the magnitude of the force of gravity exerted by the apple on the orange is the same as the force of gravity exerted by the orange on the apple.

The force of gravity between two objects can be calculated using Newton's universal law of gravitation. The force the orange exerts on the apple, and vice versa, is 2.138 x 10^-11 N. However, the apple's force on the orange is in the opposite direction.
The subject of this question is gravity, a fundamental force in physics. The force of gravity between two objects can be calculated using Newton's law of universal gravitation, which states that every point mass attracts every other point mass by a force pointing along the line intersecting both points. The equation is F = G * ((m1*m2)/r^2), where F is the force of gravity between the two objects, G is the gravitational constant (6.674 x 10^-11 N(m/kg)^2), m1 and m2 are the masses of the objects, and r is the distance between the centers of the two objects.
(a) Using this equation, we can find that the force the orange exerts on the apple is F = (6.674 x 10^-11) * ((0.20*0.12)/0.75^2) = 2.138 x 10^-11 N.
(b) According to Newton's third law of motion, every action has an equal and opposite reaction. Thus, the force the apple exerts on the orange is equal in magnitude and opposite in direction to the force the orange exerts on the apple, or -2.138 x 10^-11 N. The negative sign indicates that this force is in the opposite direction.

Answer: A. The forces on an object in motion are balanced.
Explanation:
The dynamic equilibrium is defined as the phase when an object moves at a constant velocity such that all forces on the object are balanced.
Simple case of dynamic equilibrium: A horizontal force is applied to an object making it run with a constant velocity across a surface.
Hence, the statement describes dynamic equilibrium is " The forces on an object in motion are balanced. "
So, the correct option is "A".

Answer:
The correct option is D
Explanation:
Integumentary system consists of organs including the skin which is used in the excretion of sweat.
Digestive system consists of organs including the tongue, pancrease, gallbladder and liver. The liver for example regulates toxic substances in the body and excretes a substance known as bile.
Respiratory system consists of organs including the lungs which is used to breathe in oxygen and breathe out carbon dioxide.
Urinary system consists of the kidneys, urethra, bladder and ureters; they are involved in the excretion of urine.
Circulatory system consists of the blood, the blood vessels and heart. The circulatory system also assists in the removal of carbon dioxide from the body.
Answer: D
Explanation:
b. Is the speed of Block A (greater/less than/equal to) the speed of Block B? Explain your reasoning.
c. Is the momentum of Block A (greater/less than/equal to) the momentum of Block B? Explain your reasoning.
Answer:
a. the work done by the gravitational force on Block A is less than the work done by the gravitational force on Block B.
b. the speed of Block A is equal to the speed of Block B.
c. the momentum of Block A is less than the momentum of Block B.
Explanation:
a. The work done by the gravitational force is equal to:
w = m*g*h
where m is mass, g is the standard gravitational acceleration and h is height. Given that both blocks are released from rest at the same height, then, the bigger the mass, the bigger the work done.
b. With ramps frictionless, the final speed of the blocs is:
v = √(2*g*h)
which is independent of the mass of the blocks.
c. The momentum is calculated as follows:
momentum = m*v
Given that both bocks has the same speed, then, the bigger the mass, the bigger the momentum.
The work done by gravitational force on blocks A and B is equal as the work is independent of the path. Both blocks have the same speed when they reach the final height due to the conversion of potential energy into kinetic energy. However, the momentum of Block B is greater due to its larger mass.

A nurse applies a horizontal force of 147 N on a bed that has a mass of 152 kg. The magnitude of the normal force acting on the bed is 1490 N.
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
The force applied by the nurse is horizontal, so there's no vertical component.
Therefore, the normal force is simply equal to the weight of the bed.
N = mg
N = (152 kg) (9.8 m/s²)
N = 1490 N
