Answer those 2 questions.
Tanya [424]

Answer:

Q1: c

Q2: a

Explanation:

you can tell the factors by looking at the formulas for kinetic and potential energy

for question 1  look at the formula for kinetic energy

KE=\frac{1}{2} mv^{2}

the variables needed in order to calculate an object's kinetic energy are mass and velocity.

hence, when mass and velocity changes, kinetic energy changes, showing that mass and velocity are the factors affecting kinetic energy

same thing for the second question

PE = mgh

as g (acceleration due to gravity) is considered constant (10 m/s^{2} ) it will not be considered as a factor

and thus, the factors affecting potential energy are mass and height

What does activation energy has to do with a chemical reaction.
asambeis [7]

Explanation:

Activation energy and reaction rate

The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. ... The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.

1. What is the kinetic Energy of a 1500kg object moving at 21 m/s?
Wewaii [24]
The formula for working out kinetic energy is

=122

KE = kinetic energy
m = mass of a body
v = velocity of a body


kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

For the first one I think :
Answer:
KE = 330750 J

I’m not sure about the second one- sorry

The third is
Answer:
KE = 41454 J

Hope it helps and it is correct, sorry if it isn’t !
