High energy waves have Gamma rays
velocity of the physics instructor with respect to bus

acceleration of the bus is given as

acceleration of instructor with respect to bus is given as

now the maximum distance that instructor will move with respect to bus is given as




so the position of the instructor with respect to door is exceed by

so it will be moved maximum by 3 m distance
Answer:
the rock breaks down when the wind blows particles of sand against it.
Explanation:
because the sand can easily be decomposed and temperature easily accessible to it cause line of weaknesses of the rock to break down
Answer:
The total work done by Brad each day is 176400 J
Explanation:
Hi there! The work done by a force (F) pointed in the same direction as the displacement (d) is calculated as follows:
W = F · d
The force applied is equal to the weight of Brad, that is calculated as follows:
Weight = m · g
Where:
m = mass of Brad
g = acceleration due to gravity (9.8 m/s²)
Then:
Weight = 60 kg · 9.8 m/s² = 588 N
Let´s find the vertical distance traveled by Brad each day:
He exercises 20 min per day. Each minute Brad does 60 steps. In total, Brad steps up (20 min · 60 steps/min) 1200 steps. If each step has a height of 0.25 m, the total distance traveled by Brad will be
(1200 steps · 0.25 m/step) 300 m.
Then, the total work done by Brad is
W = F · d
W = 588 N · 300 m
W = 176400 J
The total work done by Brad each day is 176400 J
Answer:
An electric motor converts electrical energy into mechanical energy. The process is as follows:
D. When current flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.
