A ball has 2 kg*m/s of momentum when thrown with a velocity of 8 m/s outwards. Find the mass of the ball.

Physics

Answer:

As, we know momentum = mass × velocity that is p = mv

we have momentum (p) = 2 kg m/s

and velocity (v) = 8 m/s

so substitute values in p=mv

2 kg m/s = m × 8 m / s

m = 2 / 8 kg = 0.25 kg

Therefore, mass of substance is 0.25 kg.

2/8 in fractional form.....

D.sound insulators prevent from being transmitted better than elastic solids

Explanation:

The correct option from the given choices is that, sound insulators prevent sound from being transmitted better than elastic solids.

Sound is a form of wave that transmits energy from one point to another.

This wave form is a longitudinal wave in nature.

During the propagation of sound, it requires a material medium to move.

Sound insulators are special materials designed not to transmit sound energy.

Such materials cuts off sound. They are better than elastic solids in preventing sound transmission.

Which type of electromagnetic radiation may damage central nervous system
Furkat [3]

Answer:

microwaves

Explanation:

microwaves do emit radiation, technically speaking, but it's not the DNA-damaging radiation we're used to hearing about. Microwaves, along with radio waves from (you guessed it) radio and cell phone towers, are types of non-ionizing radiation.

Estimate the order of magnitude of the length, in
Scrat [10]
A) a mouse, to an order of magnitude = 0.1 m ( a tenth of a meter ) That would be a big mouse but the alternatives are 1 meter or one hundredth of a meter... so go with 1/10th 

<span>b) Easy = 1 meter </span>

<span>c) two choices 10m or 100 m . Go with 100 m </span>

<span>d) Stretch it out , trunk tip to tail tip - call it 10 m </span>

<span>e) Your choice 100 m or 1000 m..... These are estimates. So long as you are within one order of magnitude you can't really be given wrong. So I'd say 100m</span>
