Answer:
The value of R₂ is equal to 24.75 ohms.
Explanation:
Given that,
Two resistors, R₁ and R₂, are connected in parallel.
The equivalent resistance is 14.5 ohms
We need to find the value of R₂.
When two resistors are connected in parallel. The equivalent resistance is given by :
So, the value of R₂ is equal to 24.75 ohms.
Answer:
a. power
b. precision
Explanation:
The hip is a spherical joint that allows the upper leg to move from front to back and from side to side. The largest joint that supports weight in the body, the hip joint is surrounded by strong ligaments and muscles.
It differs mainly with the circular articulation of the shoulder since it allows it to perform movement of greater power and with greater precision
Answer:
a. Power = 1000 Watts or 1 Kilowatts.
b. Current = 4 Amperes.
Explanation:
Given the following data;
Energy consumed = 1.8MJ = 1.8 × 10^6 = 1800000 Joules
Voltage = 250V
Time = 30 minutes to seconds = 30 * 60 = 1800 seconds
To find the power rating;
Power = energy/time
Substituting into the equation, we have;
Power = 1800000/1800
Power = 1000 Watts or 1 Kilowatts.
b. To find the current taken from the supply;
Power = current * voltage
1000 = current * 250
Current = 1000/250
Current = 4 Amperes.
Answer:
Explanation:
opposite charges attract each other, while rubbing the objects together they developed opposite charges which caused them to drift together
Answer:
(I). The initial rotation rate is 4.29 rad/s.
(II). The revolutions is 3932.
Explanation:
Given that,
Time = 1.6 h
Angular velocity = 41 rpm
(I). We need to calculate the initial rotation rate in rad/s
(II). We need to calculate the revolutions
Using formula of revolutions
Hence, (I). The initial rotation rate is 4.293 rad/s.
(II). The revolutions is 3932.
