Answer:

Circular wave

Explanation:

Circular waves are special types of mechanical waves. They all travel through a material medium or some times a vacuum.

An example of such wave is a ripple caused by dropping a stone in a tank of water.

A wave that propagates in circular form on the surface of water falls into this category.

A train car with mass m1 = 515 kg is moving to the right with a speed of v1 = 7.5 m/s and collides with a second train car. The
Anna [14]

Answer:

For the first situation, we first need to find the mass of the second train car.

In order to do that, we apply the conservation of the amount of movement:

515*7.5+m2*0=(m1+m2)*4.8

and we have as a result:

m2 = 289.6875

For the second situation, also we will apply the conservation of the amount of movement:

515*7.5-289.6875*6 = (515+289.6875)*V

and we have as a result:

V = 2.64 (it is moving to the right)

just olya [345]

Answer:

the total mass after chemical burn is 700 gram

Explanation:

Given data

glass mas s= 200 gram

chemical mass = 500 gram

total mass = 700 gram

to find out

what is the total mass after chemical burn

solution

we have given 200 gram + 500 gram = 700 gram

and we know here according to question that

container is sealed so total mass remain in container before burning and after burning

no air will release in seal container so

mass will be same as 700 gram

hence the total mass after chemical burn is 700 gram
