Answer:
The density of salt water is more than that of density of fresh water, so so salt and fresh water makes a difference in floating of ships.
all ik is it has to do with speed once you find out the formula for speed you can find out the answer

e. none of these
Explanation:
An object in FREE-FALL on the MOON would experience only acceleration
Answer:
<em>Explanation below</em>
Explanation:
<u>Friction Force</u>
When two objects are in contact, the surface between them exerts a frictional force as long as the objects are tried to move with respect to each other.
If a given external force is applied to the left, then a friction force appears to the right and opposes the intent to move them. A similar situation occurs when the force is applied to the right side.
If the object is at rest and no force is applied, no friction force appears.
It's important to recall that two different friction forces are defined: the kinetic friction force and the static friction force, usually the latter is greater than the first.
Answer:
83.847519 mV
Explanation:
B = Magnetic field strength = 7.11 mT
L = Length of steel rod = 99.1 cm
v = Velocity of steel rod = 11.9 m/s
The induced electro motive force is given by
The magnitude of the EMF induced between the ends of the rod is 83.847519 mV
