Answer:

B. The Law of Conservation of Energy

Explanation:

In Science, energy can be defined as the ability of an object or body to do work. There are two (2) main types of energy and these are;

I. Kinetic energy: it can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

II. Potential energy: it can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Additionally, the various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.

Hence, energy is never created of destroyed, it only transforms from one form to another" is the definition of The Law of Conservation of Energy.

Answer:

Le calcul du courant se fait avec deux éléments : la tension et la valeur de la résistance. Courant (A) = tension (V) / résistance (Ohm) ce qui donne la formule I = U/R.

A physics student spins a bucket of water over her head in a circular path in order to demonstrate centripetal force. She fills
Ronch [10]

Answer:

The first case requires more force to spin de bucket.

Explanation:

As we know, the centripetal force is directly proportional to the mass, the equation is given by:

F_{c}=ma_{c}

The first case has a quarter more water than the second case, therefore the first case requires more force to spin de bucket.

I hope it helps you!

A force of 31 N south is used to accelerate an object uniformly from rest to 8 m/s in 22 s. What is the mass of the object?
harina [27]

this question is centered around newtons second law f=ma

First you need to find the acceleration

acceleration = \frac{8 - 0}{22}

that gives you 0.36 recurring(on both numbers) m/s²

mass= force ÷ acceleration

mass = \frac{31}{0.36recurring}

mass= 85.25 kg

if you want to check

f=ma

85.25 × 0.36 recurring (remember its on both numbers not just 6) = 31 N
