Explanation:
The amount of matter contained inside a body is called its mass while the weight of a body is the gravitational force with which it is attracted towards the earth.
Weight, W = mg
m is the mass and g is acceleration due to gravity
The mass of the object on the moon remains the same but the weight of the body is reduced to one sixth. This is because the moon's gravity is less than the earth's gravity.
Hence, this is the main difference in the weight of the object on the earth and on the moon.
The distance PQ is 4.74 feet.
Triangle PDQ has:
If we use the Law of Cosines:
d² = p² + q² − 2 • p • q • cos(D)
d² = 2(4.24)² • [ 1 – cos(68º) ]
d = 4.74 ft

Answer:
we have an circuit with two branches in parallel,
* One formed by the switch and three light bulbs
* Another branch formed by a light bulb and the bell
Explanation:
For the construction of the circuit, let us analyze the conditions given, of the 4 light bulbs, only one should remain lit when the dapple is opened, so we must place three light bulbs and the switch in one branch and the other light bulb in the other branch.
For the bell to sound with the abort circuit it must be on the branch where the single bulb is.
Therefore we have an circuit with two branches in parallel,
* One formed by the switch and three light bulbs
* Another branch formed by a light bulb and the bell
According to Newtons first law of motion, a passenger tends to continue in the state of uniform motion even after the accident which causes the passenger to move forward.
According to the Newtons first law of motion, an object will continue in a state of rest or uniform motion unless it is acted upon by an external force. This is also known as the law of inertia.
While in a car undergoing uniform motion and suddenly the car is involved in an accident which causes the vehicle stop abruptly, a person suddenly moves forward because of the tendency to continue in the former state of uniform motion according to Newtons first law.
A seat belt helps to prevent the person from suddenly moving forward in a way that may lead to injury as a result of the accident.

Answer:
Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
