(a) the orange exerts on the apple?
(b) the apple exerts on the orange?
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.

b. in non-accelerated motion.
c. free from Earth's gravity.
Answer: B
Explanation:
When in orbit, a satellite is hold in position thanks to, between others, the earth's gravity. So the C option is discarded.
A projectile is an object thrown by the exertion of some force, like a bullet or a cannonball.
A satellite is placed in some orbit, so he can rotate the earth. The movement of the satellite is non-accelerated motion, because the only forces that act on the satellite are the forces that hold him in orbit.
When in orbit, a satellite such as the space shuttle is in non-accelerated motion and is influenced by Earth's gravity.
When in orbit, a satellite such as the space shuttle is in non-accelerated motion.
It is not simply a projectile because it is continuously under the influence of Earth's gravity.
However, it is not completely free from Earth's gravity as it continues to be pulled towards the Earth.

The first thing we must do for this case is to define a frame of reference.
We know that, the frame of reference for this case is Alana.
Therefore, the tennis ball has a speed relative to Alana.
The speed relative to Alana, is the same speed with which Alana throws the tennis ball.
Therefore, the speed of the tennis ball is:
v = 11 Km/h
Answer:
The speed of the tennis ball is:
v = 11 Km/h
Answer:
A change is said be chemical change when a change in chemical property of a substance occurs and the new substance is chemically different from old one. A change is said to be physical change when only physical properties change but chemically the substances remain same.
a) adding sugar to lemonade- It is a physical change because sugar is being dissolves in the lemonade. There is no change in the chemical property.
b) plants using CO₂ and H₂O to form O₂ and sugar is a chemical change because new products which are chemically different are formed.
c) boiling water - is a physical change because only the physical state from liquid to gas changes. Chemically water retains its properties.
d) frying an egg - the properties of egg changes after frying. Hence, it is a chemical change. A fried egg does not retain properties of an uncooked one.
e) rust forming on metal- is a chemical change. Corrosion ( rusting) is a chemical change as rust is chemically different from the metal.
f) fruit rotting - is a chemical change. When microbes act on the fruit, the fruit starts to rot.
g) removing salt from water by evaporation- it is a physical change. The salt and water retain their physical properties as mixture and when separated by evaporation process.
