AnnZ [28]

Answer:

56.7 m³

Explanation:

The radius of the circular area covered by the spill is 4.25 km

You can find the area covered by the spill by applying the formula for area of a circular surface

A=π×r² where π=3.14 and r=4.25km

A= 3.14×4.25² = 56.72 km²

Remember the total area is on average at 1 micron (1μm) thick.This is to say

1μm=1m³

So the minimum volume of oil covering the ocean surface in meters will be;

Change km² to m²

56.72 km²= 56.72×1000000=5.67×10⁷ m²

Finding the volume;

Volume = Area * thickness

Volume= 5.67×10⁷ m² * 1× 10⁻⁶ = 56.7 m³

Minimum amount of oil that was spilled is 56.7 m³

What is Force?

In the field of physics, an influence that can alter the motion of an object is referred to as a force. An object having mass can experience a change in its velocity, often known as an acceleration, when subjected to a force. Intuitively, force can also be conceptualized as either a push or a pull. Because it may be measured in both magnitude and direction, a force is considered a vector quantity.

What is atmospheric pressure?

The pressure that is exerted within the atmosphere of the Earth is referred to as barometric pressure as well as atmospheric pressure. As a unit of pressure, the standard atmosphere is defined as having a value of 101,325 Pa. This value is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

In most situations, the equation for force can be expressed numerically as

Force = pressure * A

Therefore

$F= (970 - 15 B)(\pi * (0.430 )^2)$

F= 53731 N

In conclusion, If each horse can pull with a force of 1450N

The number of horses required is

$N=\frac{60754 }{1450}$

N=37.05

a child is swinging on swing, describe what happens to both the kinectic energy and potential enegry of the child as she swings

Igoryamba

Answer:

The K.E is maximum when the child is at the vertical position and the P.E is maximum at the extreme deviated position from the vertical.

Explanation:

A child is swinging on swing up and down has both kinetic and potential energy.
The total mechanical energy of the system is conserved throughout the system. At any instant the total mechanical energy is given by,

E = K.E + P.E

The K.E is maximum when the child is at the vertical position.
The P.E is maximum at the extreme deviated position from the vertical.
And when K.E is maximum P.E becomes minimum and vice versa as per the law of conservation of energy.
