Answer:
If there is a system of magnets being held in place, there is potential energy. When you let go, the potential energy converts to kinetic energy and the magnets move. Putting the system of magnets close together which creates an opposing force.
Explanation:
Magnets cause objects to have kinetic energy by the magnetic force present in the magnet.
Magnets is a material which has a strong magnetic field which attracts ferromagnetic substances such as nickle, iron etc.
When a ferromagnetic objects put near the magnet, the magnet attracts the object and causes the movement towards its direction.
Therefore, magnets cause objects to have kinetic energy by the magnetic force present in the magnet.

A bag weighing 20 N is pushed horizontally a distance of 35 m across a
level floor by a force of 10 N, How much work is done on the bag in
Joules? W=Fd *
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J

This is so hard.
The measure of life in hours and wind is my enemy states that is a candle as it states I serve you by expiring.
What is a candle ?A candle is a stick made of wax and forms an inflammable solid substance. It has a light and gives some sort of fragrance.
It can also provide a medium to heat or to save time, as the candle is burnt the oxygen is consumed and carbon id is given out. As the statement speaks about the wind which is my enemy, it states the nature of the candle that dies out immediately.

A 1.5 kg ball is thrown at 10 m/s. What is the ball's momentum?
Answer:
[tex]\boxed {\boxed {\sf 15 \ kg*m/s}}[/tex]
Explanation:
Momentum is the product of mass and velocity.
[tex]p=m*v[/tex]
The mass of the ball is 1.5 kilograms and the velocity is 10 meters per second.
[tex]m= 1.5 \ kg \\v= 10 \ m/s[/tex]
Substitute the values into the formula.
[tex]p= 1.5 \ kg* 10 \ m/s[/tex]
Multiply.
[tex]p=15 \ kg*m/s[/tex]
The momentum of the ball is 15 kilogram meters per second.
Answer:
15 kg m/s
Explanation:
[tex]p = mv \: = 1.5 \times 10 = 15 \: kgm {s}^{ - 1} [/tex]

Answer:
D
Explanation:
The density has a formula of d = m / V.
The volumes are given as the same.
The density will be
d_lead = 113/ V
d_aluminum = 27/V
It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.
A: incorrect. If the volumes are the same, the density is not the same because the masses are different.
B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.
C: incorrect. The exact opposite is the answer.
D: Correct. This is the answer.

An airplane went from 120 m/s to 180 m/s in 4.0 seconds. What was its acceleration?
45 m/s2
15 m/s2
60 m/s2
30 m/s2
Answer:
15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2

Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss
Answer:
190 kg m/s
Explanation:
Momentum = Velocity × Mass
→ Substitute in values
2 × 95 = 190 kg m/s
The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.
What is Momentum?Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -
p = mv
It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.
Given is a boat with a mass of 95 Kg moving at 2 m/s.
Mass [m] = 95 Kg
Velocity [v] = 2m/s
We can write the momentum as -
p = mv
Substituting values, we get -
Momentum [p] = 95 x 2 = 190 Kg m/s
p = 190 Kg m/s
Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O . How many grams of water can be made from 64 g of oxygen gas?
Answer: 144 g
the mol of the oxygen gas is 64/16 = 4 (mol)
we have:
2H2 + O2 => 2H2O
4 ------> 8
=> the mol of H2O is 8 mol
=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)

Answer:
a) reactant
b) product
Explanation:
During a chemical reaction, the reactants interact among themselves in a specific temperature, pressure, pH, enzyme etc. Due to various intra and inter molecular and atomic interactions, the chemical bonds in the reactants break down. Formation of new chemical product is governed by the formation of new bond (ionic, covalent, hydrogen vander waal etc. )
