Answer:
The flow of electric charge
Explanation:
Electricity:It is defined flow of electric charge.
It is defined as the flow of charge per unit time.
Electric charge can be negative or positive .
Mathematical representation :
If charge Q flowing through the conductor and time taken in flow of charge is t seconds.
Then, current
S.I unit of current is Ampere.It is scalar quantity.
Answer:The flow of electric charge.
The answer is ”D”, “a higher frequency and a shorter wavelength.
Answer:
0.4778 m/s
Explanation:
To solve this question, we will make use of law of conservation of momentum.
We are given that the rock's velocity is 12 m/s at 35°. Thus, the horizontal component of this velocity is;
V_x = (12 m/s)(cos(35°)) = 9.83 m/s.
Thus, the horizontal component of the rock's momentum is;
(3.5 kg)(9.83 m/s) = 34.405 kg·m/s.
Since the person is not pushed up off the ice or down into it, his momentum will have no vertical component and so his momentum will have the same magnitude as the horizontal component of the rock's momentum.
Thus, to get the person's speed, we know that; momentum = mass x velocity
Mass of person = 72 kg and we have momentum as 34.405 kg·m/s
Thus;
34.405 = 72 x velocity
Velocity = 34.405/72
Velocity = 0.4778 m/s
Progressive overload is the gradual increase in stress to which we subject the body during training, where time, intensity and frequency are dimensions of it.
<h3>What is progressive overload?</h3>
It is a training principle that emphasizes a progressive intensification of stress on the muscles.
It involves the systematic application of training stimuli that force the body to adapt and grow by manipulating the variables of frequency, time and intensity.
Therefore, we can conclude that progressive overload is the gradual increase in stress to which we subject the body during training, where time, intensity and frequency are dimensions of it.

Answer:
The time is
Explanation:
From the question we are told that
The diameter of the circular saw is
The peripheral speed is
The time taken for the blade to come to rest is t = 17 s
The total acceleration of the tooth considered is
Generally the radius of the blade is mathematically represented as
Generally the tangential acceleration of the blade is mathematically represented as
Here v is the final velocity of the tooth of the blade which is zero since the blade came to rest
so
=>
Generally the total acceleration of the tooth of the blade is mathematically represented as
Here is the radial acceleration , now making the subject of the formula we have that
=>
=>
Generally radial acceleration is mathematically represented as
Here is the velocity at which the total acceleration is 130 ft/s2.
=>
=>
=>
Generally the time at which the total acceleration is 130 ft/s2. is mathematically represented as
=>
=>
