Answer: Volume

Explanation: Volume is the amount of space matter takes up. All matter takes up a certain amount of space. Volume is used in mathematics and science all the time to describe the size of a particular object.

An example of volume would be finding the volume of a cube with a length of 30 feet.

Since the length, width, and height of a cube are all equal, we can find the volume of a cube by multiplying the side × side × side or S³.

(30 ft)³

Volume = 27,000 ft³.

Which of these statements are true about scientific theories and laws?
anygoal [31]
<span>The best response would be that theories are not opinions. While laws and theories are similar, laws tend to be a collection of theories about the same phenomenon. Laws can be expressed as math formulae, but more often they're in the form of "if-then" statements. Laws and theories both have to be rigorously tested before they reach these classiffications.</span>

<u>Physics</u>

<u>Momentum</u>

Momentum Formula: P = mv

  • P is momentum (in kg · m/s)
  • m is mass (in kg)
  • v is velocity (in m/s)
<h3>Explanation:</h3>

<u>Step 1: Define</u>

m₁ = 87.2 kg

v₁ = 2.87 m/s

m₂ = 0.0520 kg

v₂ = 789 m/s

<u>Step 2: Find Momentums</u>

<em>Football Player</em>

  1. Substitute [MF]:                    P = (87.2 kg)(2.87 m/s)
  2. Multiply:                                P = 250.264 kg · m/s

<em>Bullet</em>

  1. Substitute [MF]:                    P = (0.0520 kg)(789 m/s)
  2. Multiply:                                P = 41.028 kg · m/s

<u>Step 3: Find difference</u>

  1. Define equation:                    P₁ - P₂
  2. Substitute:                              250.264 kg · m/s - 41.028 kg · m/s
  3. Subtract:                                 209.236 kg · m/s

A 1460-kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16670 N on the submar
Amiraneli [1.4K]

Answer:

a = 0.63 m/s²

Explanation:

given,

mass of submarine = 1460-kg

upward buoyant force = 16670 N

downward resistive force = 1150 N

submarine acceleration = ?

assuming g = 10 m/s²

now,

B - (R + mg) = ma

16670 - 1150 - 1460 × 10 = 1460 × a

1460× a = 920

a = 0.63 m/s²

hence, the acceleration of submarine is equal to a = 0.63 m/s²
