Answer: what do you mean ''beyond certain temperature'', Do you mean ask in cooling the liquid down or heating the liquid up?
Explanation:
Answer:
28 degree C
Explanation:
We are given that
We have to find the temperature on a spring day when resistance is 215.1 ohm.
We know that
Using the formula
Hence, the temperature on a spring day 28 degree C.
Answer:
The height of the object is 5007.4 miles.
Explanation:
Given that,
Weight of object = 200 lb
We need to calculate the value of
Using formula of gravitational force
Put the value into the formula
We need to calculate the height of the object
Using formula of gravitational force
Put the value into the formula
Hence. The height of the object is 5007.4 miles.
Answer:
a) , b)
Explanation:
a) The minimum coeffcient of friction is computed by the following expression derived from the Principle of Energy Conservation:
b) The speed of the block is determined by using the Principle of Energy Conservation:
The radius of the circular loop is:
Answer:
R = 7 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance. In this way, we have the following equation.
V = I*R
where:
V = voltage = 49 [V] (units of volts)
I = current = 7 [amp] (amperes)
R = resistance [ohms]
Now clearing R.
R =V/I
R = 49/7
R = 7 [amp]
