Two thermometers, calibrated in celsius and fahrenheit respectively, are put into a liquid. the reading on the fahrenheit scale is four times the reading on the celsius scale. the temperature of the liquid is:
The centripetal acceleration is 13.7 m/s².
<h3>Calculation:</h3>
Centripetal acceleration is given by,
Ac = v²/r
where,
Ac = centripetal acceleration
v = velocity
r = radius
Given,
v = 24 m/s
r = 42 m
To find,
Ac =?
Put the value in the formula,
Ac = v²/r
= (24)²/42
= 576/42
= 13.7 m/s²
Hence, the centripetal acceleration is 13.7 m/s².

Answer:
<h3>The answer is 19,800 J</h3>
Explanation:
The work done by an object can be found by using the formula
<h3>workdone = force × distance</h3>
From the question
force = 120 N
distance = 165 m
We have
work done = 120 × 165
We have the final answer as
<h3>19,800 J</h3>

The mass of the block is 75.7238461542 kg
Distance moved in the next 4.2 seconds
The distance moved is 20.4664723031 m
Answer:
Explanation:
Period of oscillation ∝ √ m
So period of oscillation is proportional to square root of mass
So when mass increases , period too will be increased . But the total energy will remain the same as per conservation of energy.
Hence option ( D) is the correct answer.
