Explanation:
An airplane travels 1000 miles at velocity of 500 miles in every hour. solve for the time it took the plane to arrive.
V=D/t
Answer:
Time taken by airplane to cover given distance = 2 hour
Explanation:
Given:
Distance cover by airplane = 1,000 miles
Velocity of airplane = 500 miles per hour
Find:
Time taken by airplane to cover given distance
Computation:
Time taken = Distance / Velocity(Speed)
Time taken by airplane to cover given distance = Distance cover by airplane / Velocity of airplane
Time taken by airplane to cover given distance = 1,000 / 500
Time taken by airplane to cover given distance = 2 hour

Tech A states that friction brakes lose energy as heat. Tech B states that a brake-by-wire system converts this energy into useful work. Who is
correct?
Tech A and B are correct about friction and the brake system in the statement given above.
Does brake-by-wire system converts this energy into good work?Friction that exist between brake drums and linings brings a lot of heat, and as such, it also reduces the mechanical energy of the movement of the brake drums and wheels.
Conclusively The brake-by-wire system is known to often uses the electric motor as a form of generator, that helps to reduce the vehicle by changing the car's kinetic energy into electrical energy and as such, both technicians are correct.

The material that is used to make the helmets and hand shields must be an insulator. The correct option is b.
What is an insulator?An insulator is any substance that prevents energy—such as electricity, heat, or cold—from moving through it easily. Good insulators include glass, plastic, rubber, and wood.
Insulators are substances that prevent electricity from passing through them. Insulators are employed as a defence against the potentially harmful effects of electricity because they oppose electric current. Glass, air, wood, plastic, and rubber are a few examples of insulators.
A material that is an insulator for heat and electricity must be used to make helmets and hand shields. Helmets, shields, and eye protection must not easily catch fire and be sterile-resistant.
Thus, the correct option is b.
