To solve this problem we will use the relationship given between the centripetal Force and the Force caused by the weight, with respect to the horizontal and vertical components of the total tension given.
The tension in the vertical plane will be equivalent to the centripetal force therefore

Here,
m = mass
v = Velocity
r = Radius
The tension in the horizontal plane will be subject to the action of the weight, therefore

Matching both expressions with respect to the tension we will have to


Then we have that,


Rearranging to find the velocity we have that

The value of the angle is 14.5°, the acceleration (g) is 9.8m/s^2 and the radius is



Replacing we have that


Therefore the speed of each seat is 4.492m/s
Answer:
<u>954.4m/s</u>
Explanation:
For a free falling object,it has constant acceleration and a changing velocity.
By using the velocity-time formula, the velocity can be obtained.
The height the rock travelled is the distance.
From,
Velocity (v) = Distance (d) / Time(t)
v = 3245m/3.4s
v = <u>954.4m/s</u>
That js the answer I got. Hope it's right.
The genes that are inside the chromosomes of the cell.
Answer:
The the maximum emf is 
Explanation:
Given that,
Magnetic field 
Frequency = 60 Hz
Diameter = 7.8 μm
We need to calculate the maximum emf
Using formula of emf

Where, N = number of turns
B= magnetic field
A = area
Put the value in to the formula


Hence, The the maximum emf is 
Answer:
a). 1.28333 seconds
b). 186.66 seconds
Explanation:
a). Given :
Distance between the earth and the moon, d =
m
Speed of the radio waves, c =
m/s
Therefore the time required for the voice of Neil Armstrong to reach the earth via radio waves is given by :


= 1.28333 seconds
b). Distance between Mars and the earth, d =
m
Speed of the radio waves, c =
m/s
So, the time required for his voice to reach earth is :


= 186.66 seconds
