A bowling ball of 7.0 kg will be weighed around 15.54 lbs (pounds) at the surface of the Earth.
<u>Explanation:</u>
The weight of the bowling ball as given in the question,
Since we know that the force of gravity acting on an object at the surface of the Earth is 2.22 lb i.e. the object will be weighed as 2.22 lb at the surface of the Earth. Similarly, here in this case;
The weight of the bowling ball,
Hence, the bowling ball will be weighed as 15.54 lbs at the surface of the Earth.
Answer:
Explanation:
We can use the kinematics equation to solve this problem. To find the initial vertical velocity, find the vertical component of the object's initial velocity using basic trigonometry for right triangles:
Now we can substitute values in our kinematics equation:
The heat capacity is given by the expression:
When the
is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in
, we can then determine the specific heat "C" by simply remplazing in the expression.
