Answer:

10 m/s

Explanation:

u of cue ball = 10 m/s

u of eight ball=0m/s

m of cue ball =0.16 kg

m of eight ball =0.16 kg

According to law of conservation of momentum

Momentum before collision = Momentum after collision

so

( m of cue ball X velocity of cue ball) + ( m of eight ball X velocity of eight ball)= (m of cue ball X velocity of cue ball after collision )+( m of eight ball X velocity of eight ball after collision)

thus

(0.16 X 10)+(.016 X 0)= (0.16 X 0)+ ( 0.16 X velocity of eight ball after collision)

1.6= 0.16 X velocity of eight ball after collision

1.6÷0.16= velocity of ball after collision

10= velocity of eight ball after collision

The length of spring when the block comes momentarily to rest on the compressed spring will be 0.054 m.The length of the spring by the letter x.

The energy is stored in the spring when it is stretched or compressed by some length. It is the product of mass, gravity and distance compressed or stretched. Mathrmatically it is given by;

PE=mgh

The given data in the problem is ;

m is the mass of the block is 0.5 kg height,

h is the height is released is 0.7 m

x initial length of the spring = 0.13 m.

K is the force constant of the spring = 1180 N/m.

By the law of conservation of energy,

The potential energy of the spring gets converted

[tex]\rm mgh=\frac{1}{2}KL^2 \\\\ \rm L= \sqrt{\frac{2mgh}{K} } \\\\ \rm L= \sqrt{\frac{2\times 0.5\times9.81 \times 0.7}{1180} \\\\ \\\\[/tex]

[tex]\rm L= 0.054m[/tex]

Hence the length of spring when the block comes momentarily to rest on the compressed spring will be 0.054 m

Based on scientific information, the direction that heat generally flow from is: A. hot to cold.

Heat is also known as thermal energy and it refers to a form of energy that is only transferred from an object to another due to a difference in temperature.

During the process of heat conduction, heat would only be transferred between objects that are having different levels of temperature and objects that are directly in contact with one another.

In conclusion, heat is generally transferred from a hot object to a cold object as a result of their varying temperature.

Based on the principle of conservation of momentum;

The principle of conservation of momentum states that in an isolated system of colliding bodies, momentum is conserved.

This principle can be stated mathematically as:

The average speed of each trolley is calculated using the formula:

For Trolley A:

average speed = 100 mm/0.5 = 200 mm/s

average speed of A = 0.2 m/s

For Trolley B:

distance = 200 mm = 0.2 m

average speed = 0.2 m/0.5 s

average speed of B = 0.4 m/s

Momentum = mass × velocity

Assuming direction of motion of B is positive, direction of A is negative

Momentum of A = - m × 0.2 = -0.2m

Momentum of B = m/2 × 0.4 = 0.2 m

Total momentum = 0.2 m - 0.2 = 0

Therefore, the total momentum before and after the release of the spring is zero.

After years of observation, Hubble made an extraordinary discovery. In 1923 he spotted a Cepheid variable star in what was known as the Andromeda Nebula. Using Leavitt's techniques, he was able to show that Andromeda was nearly 1 million light years away and clearly a galaxy in its own right, not a gas cloud.

Answer:

1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.

2. The image cannot be projected onto a screen also.

3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.

Thanks!

Answer:

becaise the light does not actually pass through the image

Solar eclipse happens when the moon get in between the sun and earth. It blocks sun light and causes its shadow over the sun as seen from earth.

Lunar eclipse happens when the earth is in between the sun and moon. It blocks sun light from reflecting off the moon surface so there is a shadow on the moon as seen from earth.

The current in the wire has created a magnetic field with its north pole at the top of the rod. This is because the magnetic field influences electric currents. Thus, the correct option is C.

A magnetic field is a vector field which describes the magnetic influence on a moving electric charge, electric current, and magnetic material. A moving charge in a magnetic field which is experienced a force perpendicular to the own velocity and to the magnetic field.

The magnetic field is also referred to as the field where magnetic forces act to shape an electrical current. The only material or body which is capable of altering an electrical current in a magnetic field is the presence of another magnetic field in the space.

Therefore, the correct option is C.

I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

I study if the volume or density of items determines whether solid objects float or sink in water in this scientific inquiry I did the experiment of density, mass, and volume using a rock and a standard-shaped piece of wood.

It is critical that the chosen piece of wood is larger than the rock and that the rock be tiny enough to fit inside the measuring cylinder. I see both the rock and a chunk of wood.

Hence I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.
