Answer:
60 to 80%
Explanation:
For maximum benefit, the heart rates during exercise regimes should be between<u> 60 to 80% </u>of an individual's maximum heart rate.
<em>The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;</em>
<em> 220 - 40 = 180 beats per minute.</em>
Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.

Answer:
t = 2.2 s
Explanation:
Given that,
Height of the roof, h = 24.15 m
The initial velocity of the pumpkin, u = 0
We need to find the time taken for the pumpkin to hit the ground. Let the time be t. Using second equation of kinematics to find it as follows :
Here, u = 0 and a = g
So, it will take 2.22 s for the pumpkin to hit the ground.
When you ride your bike around a corner at 10 m/s, you are accelerating. Acceleration is caused by any forces. Sliding friction keeps you in the seat when a car goes around a corner. If you throw a ball into the air, Earth exerts a force on the ball.
The sun is at the solstices on roughly June 21 and December 21.
June 21 is the "Summer" solstice in the Northern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Cancer, about 23.5° North of the equator.
December 21 is the "Summer" solstice in the Southern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Capricorn, about 23.5° South of the equator.
