0.8 mj of energy are used by a blender in 3 and a half minutes what is the power rating on the blender
1 answer:
Answer:
Power rating on the blender = 3809.52 Watts
Explanation:
We have expression for power equal to ratio of work and time,
Energy used by blender = Work done by electricity = 0.8 MJ =
Time of using blender = 3.5 minutes = 210 seconds
So power of blender = 800000/210 = 3809.52 Watts
Power rating on the blender = 3809.52 Watts

Answer:
Maximum starting velocity that the car can possess if the stuntman is to be successful = 50 m/s
Explanation:
We have equation of motion ,
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this case, displacement = 100 meter, acceleration = -8
, time = 10 seconds, we need to find initial velocity.
Substituting
So, Maximum starting velocity that the car can possess if the stuntman is to be successful = 50 m/s
Maximum starting velocity that the car can possess if the stuntman is to be successful = 50 m/s
Explanation:
We have equation of motion ,
In this case, displacement = 100 meter, acceleration = -8
Substituting
So, Maximum starting velocity that the car can possess if the stuntman is to be successful = 50 m/s
