Genes. you inherit 50% from your mom and dad. I believe that is the answer....
I believe your answer should be C. Speed.
<u>Answer:</u>
Prior to exercise, a proper warm-up of 10-15 minutes is extremely important to avoid injuries.
- Don't go too hard in the beginning and boost your activity level slowly. A good indication of a proper warm-up is that you feel sweat on your body parts.
- Don't overstretch right in the beginning as it can cause sore in your muscles and joints or stress fractures.
- Take a break if you feel sick or fatigues and use other drinks along with water to replace electrolytes and body fluids.
The acceleration due to gravity at the Earth's surface is 9.8 m/s/s
<span>So a 2 kg object will accelerate at 9.8 m/s/s if it is dropped..... actually all dropped objects will accelerate at the same rate. </span>
<span>The force of gravity on the object is given by Newton's 2nd Law </span>
<span>F = m . a </span>
<span>F = 2 . 9.8 = 19.6 N </span>
<span>Now go to Mars , with a lower gravitational field strength. It only accelerates falling objects at 3.71 m/s/s </span>
<span>So the force of gravity on the object is F = 2 . 3.71 = 7.42 N </span>
<span>But the answer is (2) 2 kg, because the mass of the object stays the same and that is what you are asked for. </span>
<span>Someone was trying to be tricky.</span>
A is the answer mass and force
