Answer:
A) True
C)True
D)True
Explanation:
As we know that power is the rate at which work is done.
We know that mechanical work w given as
w = ∫F.ds
F=Force
ds = Elemental displacement
So power P = F.V
V=Velocity
F=Force
The unit of power in SI unit is Watt or joule per second (J/s).But on the other hand the unit of power in English system is horsepower.
The is also can be defined as the rate at which energy is transformed.
Following option are corrects
A) True
C)True
D)True
Examples of student-led organizations are:
- Academic and educational organizations
- Community service organization
- Media and publications organizations
- Political or multicultural organizations
- Recreation and sports organizations
- Student government organizations
- Religious and Spiritual organizations
The benefits of getting involved in any of these are many. They include but are not limited to:
- It helps one to learn more about oneself
- It is a great place to develop leadership skills
- It offers the opportunity for people to build life-long networks
- Skills learned in class can be practiced and honed in these organizations
- Soft skills such as team-intellignce, and social intelligence can be learned in these organizations
- Valuable experiences that count in real-life jobs can be learned here
- It is also an opportunity to give back to the community and to have fun

The biological process that directly converts energy from the Sun into chemical energy would be Photosynthesis. It is a process carried out by autotrophic organisms which are predominantly plants and other photosynthetic bacteria.
The complete question is missing, so i have attached the complete question.
Answer:
A) FBD is attached.
B) The condition that must be satisfied is for ω_min = √(g/r)
C) The tension in the string would be zero. This is because at the smallest frequency, the only radially inward force at that point is the weight(force of gravity).
Explanation:
A) I've attached the image of the free body diagram.
B) The formula for the net force is given as;
F_net = mv²/r
We know that angular velocity;ω = v/r
Thus;
F_net = mω²r
Now, the minimum downward force is the weight and so;
mg = m(ω_min)²r
m will cancel out to give;
g = (ω_min)²r
(ω_min)² = g/r
ω_min = √(g/r)
The condition that must be satisfied is for ω_min = √(g/r)
C) The tension in the string would be zero. This is because at the smallest frequency, the only radially inward force at that point is the weight(force of gravity).
The power required to force the current of 4.13 A to flow through the conductor is 1927.43 watts
<h3>What is power? </h3>
This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:
Power (P) = square current (I²)× resistancet (R)
P = I²R
<h3>How to determine the power</h3>
- Current (I) = 4.13 A
- Resistance (R) = 113 ohms
- Power (P) =?
P = I²R
P = 4.13² × 113
P = 1927.43 watts
Thus, the power required is 1927.43 watts
