Answer:
B
Explanation:
A normal heart rate is from 85-95% the other heart rate is not normal because your heart is beating more than normal
As the climber climbs the mountain, he needs to over his or her own weight component along the slope of the mountains.
By Newton's second law: Net force = Mass x acceleration
Hence, greater the mass, greater will be the force required to move up the mountain. Hence, the climber will need to apply higher force to climb up as he or she has packed too much, which resulted in the increase in the mass. Hence, there is a increase in the force which will pull him or her downward.
Answer:
f = 8 N
Explanation:
Data provided in the question
Radius of the pulley = r = 0.05 m
Moment of inertia = (I) = 0.2 kg.m^{2}
Angular acceleration = ∝ = 2 rad/sec
Based on the above information
As we know that
Torque is
And,
Torque is also
So,
We can say that
0.05f = 0.4
f = 8 N
We simply applied the above formulas
Explanation:
Mass of the car = 2000N / 10 = 200kg.
Fnet = ma. Assuming there is only the horizontal force acting on the car, then
F = (200kg)(3.3m/s²) = 660N.
