Answer:
a. The apparent depth of the object is less than the real depth.
Explanation:
When we observe for any object lying at the bottom of the pool from the edge of the pool then we are actually viewing an object from an optically rarer medium into an optically denser medium.
The schematic shows the apparent view of the object due to the bending of the rays coming form the object to our eyes.
The rays when coming from a denser medium to a rarer medium they bend away from the normal of the interface.
Take left to be the negative direction, and right to be positive. That means the forces on the squirrel would be -2N and 3N.
Add all the forces to find the net force on the squirrel. -2N+3N=1N
Because the positive direction is to the right, the net force of 1N is directed to the right.
Answer:
The pressure is 10 MPa in the area acting the force of N
Explanation:
The pressure units in Pascal so, P= 10 Mpa because can put Mega as a name.
A: A disease which infects the baby mice shortly after birth
It is absolutely true that when the velocity of an object
changes, the momentum of the object also change. Momentum of any object is
defined as the multiple of velocity of an object and the mass of the object. So
we can easily deduce that momentum is directly proportional to velocity of an object
if the mass of the object remains constant. So it can be seen that if the mass
of the object does not change then any change in velocity is bound to have an
effect on the momentum of the object. We can easily write the equation as
momentum= mass x velocity.
