Answer:
The answer to your question is: W = 2063.4 J
Explanation:
Data
Force = 157 N
angle = 25°
distance = 14.5 m
W = ?
Process
- Find the horizontal force
cos Ф = adjacent side / hypotenuse
adjacent side = hypotenuse x cosФ
a.s. = 157 x cos 25
a. s. = 142.3 N
- Find the work
W = F x d
W = 142.3 x 14.5
W = 2063.4 J
Electrical shock is most likely to be fatal when the path of the current is through the heart.
Answer:
1440 W
Explanation:
The power drawn by a voltage source is the rate of energy consumed, and it can be written as:
where
V is the voltage
I is the current
P is the power
For the source in this problem we have:
I = 12 A is the current
V = 120 V is the voltage of the source
Solving for P, we find the power:
Answer:
Part a)
When rotated about the mid point
Part b)
When rotated about its one end
Explanation:
As we know that the angular acceleration of the rod is rate of change in angular speed
so we will have
Part a)
When rotated about the mid point
now torque is given as
Part b)
When rotated about its one end
now torque is given as
False, you pass a light through a mixture If the light bounces off the particles, you will see the light shine through and you have a colloid mixture
