Answer:
Temperature – cooler stars are red, warmer ones are orange through yellow and white. The hottest stars shine with blue light. Age – As a star ages it produces different chemicals which burn at different temperatures.
The answer is v=2.00 m/s per second for the 10 seconds
As we have all learned from Newton #3, every action has an equal, opposite reaction.
The force that the football exerts on the kicker's foot is equal to the force with which the kicker's foot impacts the ball. (100 N)
fulcrum to get the correct mechanical advantage?
Answer:
The distance of load from fulcrum is 5 m.
Explanation:
Given:
Mechanical advantage, MA = 0.4
Distance of force from fulcrum is,
Distance of load from fulcrum is,
We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.
So, Mechanical advantage is given as:
Therefore, the distance of load from fulcrum is 5 m.
2. The Moon takes 27.25 days to make one revolution around the Earth. Calculate how
many seconds it takes for the Moon to make one revolution around the Earth.
Answer:
1. 15.64 m/s
2. 2,354,400 seconds
Explanation:
1. 1mile is equivalent to 1609metres and 1hour is equivalent to 3600sec.
35mph = (35×1609)/3600
= 56315/3600
= 15.64 m/s
2. Note that 1 day ===> 24hrs
60min ==> 1hr
60sec ===> 1min
Thus 27.25 days = 27.25×24×60×60
= 2,354,400 seconds
Answer:
Mechanical energy
Explanation:
The mechanical energy in a mechanical system is the summation of its kinetic energy and its potential energy.
Mechanical Energy= Potential Energy +Kinetic energy
Potential energy is defined as the energy stored in a stable object and kinetic energy is defined as the energy of a moving object or energy required in the motion of a object.
Answer:
mechanical energy
Explanation:
i believe thats the answer hope that helps
