Answer:
122.76J
Explanation:
Given data
work done= 372 Joules
efficiency= 33%
Required
We want to compute the value of the work that is 33%
= 33/100* 372
= 0.33*372
= 122.76J
Hence 122.76J of work is transferred from the engine to the exhaust
Water<span> can </span>dissolve salt<span> because the positive part of </span>water<span> molecules attracts the negative chloride ions and the negative part of </span>water<span> molecules attracts the positive sodium ions. The amount of a substance that can </span>dissolve<span> in a liquid (at a particular temperature) is called the solubility of the substance. So the solute is the salt and the solvent is the water. I believe that is correct.</span>
Answer:
the strength of magnetic field at B is 256
Explanation:
When you start sliding the couch, you have to overcome the static friction of the carpeted floor, which is usually very big, especially due to the texture of the carpet. However, as long as you get it moving, you only have to apply the force to overcome the kinetic friction, which is smaller than the static friction.
