Answer:
a).
b).
Explanation:
For the block that stays on the track, its maximal height is attained when all of the kinetic energy is converted to potential energy
a).
The height for the block on the longer track can by find using this equation:
Cancel the mass as a factor in each element in the equation
b).
The other lost some kinetic energy so, use a projectile motion to determine the total height for the other bock:
Solve to v'
Answer: X-rays
The range of X-rays goes from 1x10^-8 to 1x10^-11.
Answer:d= 0.0219m
Explanation:
P= force /area
Area =πr^2=πd^2/4
πd^2/4=force/pressure
πd^2/4=34/90000
πd^2/4=0.0003778
πd^2= 0.0003778*4
πd^2=0.001511
Since π=3.142
d^2= 0.001511/3.142
d^2= 0.000480
d= square root of 0.000480
d= 0.0219m

Answer:
60 m/s
Explanation:
acceleration: 1/2 m/s2
time: 2 minutes
there are 60 seconds in one minute so
60sec x 2 min = 120 sec
1/2 in decimal form is 0.5 so 0.5 x 120sec= 60m/s
