Answer:
#See solution for details.
Explanation:
-Mechanical advantage is the ratio of input force to an output force.
-Let the length of the inclined plane be x and the height be y.
-The mechanical advantage is calculated as:
Hence, the inclined plane increases the force being exerted by times.
Answer:
The temperature change per compression stroke is 32.48°.
Explanation:
Given that,
Angular frequency = 150 rpm
Stroke = 2.00 mol
Initial temperature = 390 K
Supplied power = -7.9 kW
Rate of heat = -1.1 kW
We need to calculate the time for compressor
Using formula of compression
Put the value into the formula
We need to calculate the rate of internal energy
Using first law of thermodynamics
Put the value into the formula
We need to calculate the temperature change per compression stroke
Using formula of rate of internal energy
Put the value into the formula
Hence, The temperature change per compression stroke is 32.48°.
Answer: a = 200 Ω, b = 7.5 mA
Explanation:
Re = 100 + 100 = 200 Ω
I = E/R = 1.5/200 = 0.0075 A
