Answer:
It will always have a zero acceleration
Answer:
The voltage across a semiconductor bar is 0.068 V.
Explanation:
Given that,
Current = 0.17 A
Electron concentration
Electron mobility
Length = 0.1 mm
Area = 500 μm²
We need to calculate the resistivity
Using formula of resistivity
Put the value into the formula
We need to calculate the resistance
Using formula of resistance
We need to calculate the voltage
Using formula of voltage
Put the value into the formula
Hence, The voltage across a semiconductor bar is 0.068 V.
Answer:
Being an elastic object, rubber ball will be an ideal choice as it will bounce off the bowling pit and will experience a large change in momentum in comparison with the beanbag which will either slow down or come to a halt upon hitting a bowling pit. That is why rubber ball will experience a greater impulse and the bowling pin will experience the negative impulse of the rubber ball.
For Rubber Ball
Upon elastic collision it will reverses the direction and move with velocity equal or less then original
change in momentum = P
For Beanbag
value of impulse will large if velocity is zero.
