Answer:
1.78 x 10² kg
Explanation:
KE = ½mv²
m = 2KE/v² = 2(2e4)/(54/3.6)² = 177.777...
Answer:
<h2>Yes,</h2>
BMI is a simple indicator of weight for height and can't differentiate between muscle mass and fat mass. So BMI tends to overestimate the health risk for adults with a high muscle mass, such as some athletes, and underestimate the risk for adults with a low muscle mass, as can occur with sedentary lifestyles.

Answer:
187.38 m
Explanation:
Using the equation of motion
s = ut + 1/2gt²...................... Equation 1
Where s = distance of fall, u = initial velocity of the rock, t = time taken for the rock to fall from rest, g = acceleration due to gravity of venus.
Given: u = 0 m/s ( from rest), t = 6.5 s, g = 8.87 m/s².
substituting into equation 1
s = 0(6.5) + 1/2(8.87)(6.5)²
s = 0 + 374.7575/2
s = 187.38 m.
Hence the rock will fall 187.38 m
The correct answer is "True."
Further Explanation:
When a person first sees someone they are interested in they may have feelings of infatuation. When a person feels this they may believe it is love, but it is a significant level of the dopamine and norepinephrine that is being released into the brain.
After a while, when the infatuation subsides, the person may not have the same feelings as before since the levels have subsided. These substances control several emotions in the brain such as cravings for food, desires, and even a person's motivation.
