Answer:
d) Agility
Explanation:
Agility is defined as the capability or ability of the body to change the position of the body efficiently, and it requires the isolated movement's integration skills by using a combination of speed, balance, reflexes, coordination, strength, and endurance.
In the field of sport, it is categorized in a unique sport because it is a combination of various factors.
Therefore, agility is a component that is related to skill-related physical fitness.
Efficiency- How much energy is wasted and how much useful energy is produced
Money- How expensive to install them
Location- She has to consider the location where she places them so that there is enough sunlight and light energy for the solar panels, obviously she should have solar panels if the location receives a sufficient amount of sunlight
Answer:
Mass of the skater, m = 72.75 kg
Explanation:
It is given that,
Radius of the circular path, r = 31 m
Speed of the skater, v = 14 m/s
Centripetal force, F = 460 N
We need to find the mass of the skater. It can be determined using the formula of centripetal force. It is given by :
m = 72.75 kg
So, the mass of the skater is 72.75 kg. Hence, this is the required solution.
Answer:
D. wood, hydrogen gas, milk, and water
Explanation:
Waves will transmit through wood, hydrogen gas, milk and water.
Waves are disturbances that propagates energy usually through a material medium.
Most mechanical waves pass through the given medium. Only electromagnetic waves do not really require a material medium for their propagation. They can be propagated through a vacuum.
Answer:
Torque = 1191.68 N-m
Explanation:
Given data
mass m = 76 kg
standingdistance r = 1.6 m
Solution
we get here torque that si express as
torque = force × distance ................1
torque = r × F sin(theta)
and we know that
F = mg .........2
and g = 9.8 m/s²
put here value in equation 1 we get
Torque = 76 × 1.6 × 9.8 × sin(90)
Torque = 1191.68 N-m
