Sup Milk,

Sublimation = Energy is absorbed and a solid turns to a gas.

Condensation = Energy is released and a gas changes to a liquid.

Evaporation = Energy is absorbed into a liquid to turn it into a gas.

Answer:

(i) Energy is absorbed into a liquid to turn it into a gas is called as evaporation. For example. consider water where heating to its boiling point will turn the liquid into vapor known as evaporation.

(ii) Energy is absorbed and a solid is turned into a gas is called sublimation.

(iii) Energy is released and a gas changes to a liquid is called condensation which is the reverse process of evaporation.

Here it is an application of Newton's III law

as we know by Newton's III law that every action has equal and opposite reaction

So here as we know that two boys jumps off the boat with different forces

from front side of the boat the boy jumps off with force 45 N which means as per Newton's III law if boy has a force of 45 N in forward direction then he must apply a reaction force on the boat in reverse direction of same magnitude

So boat must have an opposite force on front end with magnitude 45 N

Now similar way we can say

from back side of the boat the boy jumps off with force 60 N which means as per Newton's III law if boy has a force of 60 N in backward direction then he must apply a reaction force on the boat in reverse direction of same magnitude

So boat must have an opposite force on front end with magnitude 60 N

So here net force due to both jump on the boat is given by

$F_{net} = F_1 - F_2$

$F_{net} = 60 - 45$

$F_{net} = 15 N$

so boat will have net force F = 15 N in forward direction due to both jumps

calculate the value of net force acting on given body?5N acting towards right & 15N force acting towards left on the brick.(

lys-0071 [83]

Answer:

The net force acting on the body is 10N directed to the left.

Explanation:

Magnitude of force to the right = 5N

Magnitude of force to the left = 15N

Net force acting on the object and in what direction;

Solution:

It is the vector sum of all forces acting on a body. This net force is the single force that will replace the forces acting on a body;

For the problem;

Net force = Force to the left + Force to the right

Let us take left to be negative and right to be positive;

Force to the left = -15N

Net force = -15N + 5N = -10N

The net force acting on the body is 10N directed to the left.

When turning a magnet very quickly would be BEST used to create A) radiation. B) light waves. C) an electric current. D) a conve

Gre4nikov [31]

the correct choice is

C) an electric current.

as a magnet is turned quickly relative to a coil, the magnetic flux linked with coil varies due to variation of angle of direction of magnetic field with normal to the plane of coil. the coil resist this change of magnetic flux in it by inducing emf in it so as to nullify the variation in magnetic flux. Due to this induced emf , electric current flows through the coil.
