D, releases a massive amount of energy as heat Hope this helps
Answer:
Explanation:
The center of gravity will act at the middle point that is at 4.38 m from the end of the plank that is on boat . 16.35 x 9.8 N will act at this point .
The plank will turn around a point at 3.17 m from the end of plank that is on boat .
Suppose the weight required be W . It will be placed at the end of the plank that is on boat . The position of man is on the extreme end of the plank that is over water . So its distance from turning point will be 8.76 - 3.17 = 5.59 m .
Taking torque about turning point of all the forces like , weight of plank , weight of the person walking and force due to W
W x 3.17 = 16.35 x ( 4.38 - 3.17 ) + 60.3 x ( 8.76 - 3.17 )
W x 3.17 = 19.78 + 337.07 = 356.85
W = 112.57 kg .
Two objects allowed to move freely will accelerate toward each other
in response to the gravitational forces between them.
It doesn't matter whether they have equal masses or vastly different
masses ... each object accelerates toward the other one.
The less-massive object has greater acceleration, and the more-massive
object has smaller acceleration.
Yes. When you fall to the Earth, the Earth falls to you, but with less
acceleration because it has less mass than you have.
Answer:
The charge on the droplet is .
Yes, quantization of charge is obeyed within experimental error.
Explanation:
Given that,
Radius = 1.6μm
Electric field = 46 N/C
Density of oil = 0.085 g/cm³
We need to calculate the charge on the droplet
Using formula of force
Put the value into the formula
We need to calculate the quantization of charge
Using formula of quantization
Put the value into the formula
Yes, quantization of charge is obeyed within experimental error.
Hence, The charge on the droplet is .
Yes, quantization of charge is obeyed within experimental error.
