Answer:
False.
Explanation:
Removing the radiator cap will harm you. If the engine is hot and you open the radiator cap then it will cause the liquid boil, pushing the coolant out of the radiator and spraying around the liquid which can harm the person who is opening that cap. So you should aware of the risk and be prepared to avoid danger.
These values when compared seem to be the same. They are equal. If we convert them to the same units, they results to the value which is:
51.5 Hectograms = 5100 Grams
51,500 Decigrams = 5100 Grams
Hope this answers the question. Have a nice day.
Complete Question
The diagram of with this question is shown on the first uploaded image
Answer:
The value is 
Explanation:
From the question we are told that
The mass of the rock is 
The length of the string is 
The angle the string makes horizontal is 
The angle which the projection of the string onto the xy -plane makes with the positive x-axis is 
The angular velocity of the rock is 
Generally the radius of the circle made by the length of the string is mathematically represented as

=> 
=> 
Generally the resultant tangential velocity is mathematically represented as

=> 
=> 
Generally the tangential velocity along the x-axis is

=> 
=> 
The negative sign show that the velocity is directed toward the negative x-axis
Generally the tangential velocity along the y-axis is

=> 
=> 
Generally the tangential velocity along the y-axis is

=> 
Generally the tangential velocity at that instant is mathematically represented as
