On April 15, 1912, the luxury cruise liner Titanic sank after running into an iceberg. What was the cruise liner’s speed when it

collided with the iceberg if it had a mass of 4.23 x 108 kg ship and a momentum of 4.9 x 109 kg·m/s?

The cruise liner’s speed when it collided with the iceberg if it had a mass of 4.23 x 108 kg ship and a momentum of 4.9 x 109 kg·m/s is v= 11.584 m/s

Explanation:

Given :

The cruise liner’s speed when it collided with the iceberg has a

Mass (m) = 4.23 x 108 kg  and

Momentum (p) = 4.9 x 109 kg m/s

To calculate the momentum,

We need to use the formula of a momentum

Momentum = Mass x Velocity ( p = m v )

as we need to find the velocity the formula becomes

velocity = momentum / mass

v = p / m

= (4.9 x 109 kg m/s) / (4.23 x 108 kg)

v= 11.584 m/s

The sun produces large amounts of energy. By what process does the sun produce energy?
AlladinOne [14]
The sun produces energy by converting gravitational potential energy into radiation via quantum processes in the nucleus of the atoms.

Since the mass of the sun and it's temperature are not quite enough to generate nuclear FUSION on their own, quantum tunneling is the primary process by which nuclear fusion occurs in our sun, SOL. FISSION also occurs as a result of this fusion.

Additionally, gravitational potential energy is also the reason that supernovae are so bright. Cool!

Gravity is defined as: Select one: a. an apple falling from a tree toward the ground. b. ability to accomplish a job with the le
Scorpion4ik [409]

Answer:

c. natural force or pull toward the earth

Explanation:

Gravity of the earth is the force of attraction that it naturally possesses to attract any mass.

An apple falls on the earth due to this force of gravity.

The force of gravity near to the surface of the earth is given as:

F=m.g

where:

m= mass of the body

g= acceleration due to gravity

The variation of the gravitational force with height is given as:

F'=m.g'

where:

g'=g\times (1+\frac{h}{R} )^{-2}

where

R = radius of the earth \approx64000\ km

Jessica is running a 10K. She alternates between running and walking each kilometer. She runs at a rate of 1 kilometer every 5 m
saveliy_v [14]

Answer:

c.100 minutes

Explanation:

Total distance = 10 km

Runs for 1 km every 5 minutes

walks 1 km every 15 min

She alternates between walking and running  so,  Jessica will walk 5 km and run 5 Km

Time taken by Jessica for walking : 5 km

Time taken to walk 1 km=5 minutes

Time taken to walk 5 km

=> 5 X 5

=>25 minutes

Time taken by Jessica for Running : 5km

Time taken to run 1 km = 15 minutes

 

=> 5 X 15

=>75 minutes

Total time taken   = Time taken by Jessica for walking + Time taken by Jessica for Running

=>25 minutes +75 minutes

=> 100 minutes

With a force of 5 newtons, Amanda pushes the stack of books to the right. At the same time, Jeremy, her little brother, pushes t
Vaselesa [24]
Its letter C. 5N to the left. Since Jeremy's force in Newtons are higher than Amanda's (in newtons), and since Jeremy's force directs to the left, then the direction of the force will be to the LEFT. Then subtract the higher one to the lower one so that would be: 10N-5N=5N. So it is C. 5N to the left.
