A kangaroo hops at an angle of 25° to the horizontal with a velocity of 20 m/s. What is the vertical component of the velocity? A. 8.5 m/s B. 12.5 m/s C. 18 m/s D. 20 m/s

Answers

Answer 1
Answer:

Answer:

A. 8.5 m/s

Explanation:

vᵧ = v sin θ

vᵧ = (20 m/s) (sin 25°)

vᵧ = 8.5 m/s

Answer 2
Answer:

I took the test and got A) 8.5 correct

What is the weight of a 45 kg box? N

Answers

45 kg * 9.8 m/s^2 = 441 N.

Answer:

The force of a mass's weight is defined as its mass * acceleration due to gravity.

On Earth, g is about 9.8 m/s^2. This will be the acceleration due to gravity.

Then, 45 kg * 9.8 m/s^2 = 441 N.

What is Newtons 2nd law of motion?

Answers

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

50 POINTS! Why is the Ocean harder to explore than Outer Space, besides the water pressure? :D

Answers

Going that deep into the water it can get very hot in the submarine  , whether you believe it or not , it also causes problems when you come back to the surface. The gravity is not the same under water as it is on land . 

In some parts of the ocean the Carbon levels are really high.

In the ocean there are many unknown species and we do not actually know what is down there or what could attack us.

Although we can make lots of forms of light , down in the ocean it is very dark so we can't see basically anything , unless there is a fish that can glo , in the ocean there are many of those .

Also we do not "yet" have a way for gas of a fan powered sub to run for multiple hours
 ( months or days)

I hope this helps
Based on precise facts, scientists have only studied 1% of the Ocean. Imagine that. Why is this so?

This is on the grounds that investigating the seas is more troublesome than investigating the Moon and space. It's genuinely simple to construct a little spaceship to hold weight. The world is full of water. About 70%. So imagine going deep down into the water and exploring all parts of the globe. Scientists haven't created a good equipment to dive deep down into the ocean.
