A 4 kg rock is rolling 10 m/s find its kinetic energy

Answers

The answer is 200 J

The kinetic energy (KE) is:
KE = 1/2 m * v²
m - mass of the object
v - velocity of the object

We have:
m = 4 kg
v = 10 m/s

KE = 1/2 * 4 kg * 10² m/s
KE = 200 J

A runner is traveling around the track below at a constant speed. Is she accelerating? A. Yes, she is accelerating because her speed is constant.

B. Yes, she is accelerating as she turns and changes direction.

C.No, she is not accelerating because there is not an incline to the track.

D.No, she is not accelerating because her speed is constant.

Answers

ANSWER:

D.No, she is not accelerating because her speed is constant.

EXPLANATION:

The rate of change of velocity with respect to time is known as acceleration.

acceleration =change in velocity/time

As she is running at constant speed and there is no change in velocity so she is not accelerating.

How many moles of oxygen react with hydrogen to produce 22.8 mol of H2O? The balanced equation is as follows: 2H2 + O2 → 2H2OHow many grams of CO2 are produced if 35.48 mol of HCl are reacted according to this balanced chemical equation? CaCO3 + 2HCl → CaCl2 + CO2 + H2O

Answers

2H₂ + O₂ → 2H₂O
$(22.8 mol H2O)/(1)$ * $(1mol O2)/(2 mol H2O)$ =
11.4 mols O₂

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O
$(35.48molHCl)/(1) * (1 mol CO2)/(2 mol HCl) * (44.01 grams CO2)/(1 mol CO2)$ =
780.7 grams CO₂
