1 answer:
Fittoniya [83]3 years ago
4 0

Answer:

21s

Explanation:

Given parameters;

Radius  = 10m

Speed or velocity  = 3m/s

Unknown:

Period  = ?

Solution:

To solve this problem, use the expression:

      v  = \frac{2\pi r}{T}  

r is the radius

T is the unknown

           Input the parameters and solve for T;

    3  = \frac{2 x \pi  x 10}{T}  

    62.84 = 3T

         T  = 21s

We think of the response of the circuit as the ratio of the maximum current to the maximum voltage provided. Explain why the rat
nexus9112 [7]

Answer:

Z = R, i = V/Z,    w = √1 / LC

Explanation:

In an RLC circuit the impedance of the circuit is

          Z = √[R² + (X_{L} - X_{C})²

Where

      X_{L} = wL

      X_{L} = 1 / wC

They are the reactances of the inductor and the capacitor, in this case the current advances to the voltage in the first and is delayed from the voltage in the second, so when the two values ​​give the same reactance the current goes in phase with the voltage and the impedance is minimal

          Z = R

          V= i Z

           i = V/Z

Therefore the current is maximum, this occurs when

       w = √1 / LC

Saying that this is the resonant frequency

If a force of 12 N is applied to an object with a mass of 2 kg, what will be its acceleration?
nadezda [96]
F = ma,  Where F is force is in N, mass is in kg, = 2kg, a is acceleration in m/s²

12 = 2a

2a = 12

a = 12/2

a = 6

Acceleration = 6 m/s²

Gravitational force on the moon is only 1/6 that of the gravitational force on earth. what would be the weight of a 10-kg object
MA_775_DIABLO [31]
According to Newton's Second Law of Motion, the force is equal to the mass of an object multiplied by its acceleration. When you talk about gravitational force, the acceleration referred to here is the acceleration due to gravity. This is very familiar to us in physics. The acceleration due to gravity on Earth is equal to 9.81 m/s². It actually depends on the location. According to the Universal Law of Gravitation:

F = Gm₁m₂/d²

The force is a factor of the product of two masses and their distance from each other. The G is a constant called the universal gravitational constants. So, gravitational force is actually a relative force exerted by one body to another. 

Going back the Second Law of Motion, we can modify the equation to:

F = mg

Since it is mentioned that the gravity on the moon is only 1/6 of the Earth, then the gravity for moon is:
g,moon = 1/6(9.81) = 1.635 m/s²
So, let's compare the weight of the object with a mass of 10 kg. The weight is actually the force due to gravity pulling you towards the center of the body.

Weight on Earth = (10 kg)(9.81 m/s²) = 98.1 N
Weight on Moon = (10 kg)(1.635 m/s²) = 16.35 N

The mass, on the other hand, is not affected by gravity. It is always constant. Therefore, the mass of the object on the moon is the same with its mass on the Earth.
