Titanium's specific heat capacity is 0. 523 j/g*k. how many joules of heat are required to raise the temperature of 2. 50g of ti
1 answer:
The amount of heat required to raise the temperature is 706.05J.
To find the answer, we need to know more about the specific heat capacity.
<h3>How to find the heat required to raise the temperature?</h3>- Specific heat can be defined as, the amount of heat needed to increase a substance's temperature by one degree for every gram.
- We have the expression for amount of heat required to raise the temperature from T1 to T2 as,
Q=msΔT
- We have given with the following values,
- Thus, the amount of heat required to raise the temperature is,
Thus, we can conclude that, the amount of heat required to raise the temperature is 706.05J.

Answer:
Acceleration of the object is .
Explanation:
It is given that, the position of the object is given by :
Velocity of the object,
Acceleration of the object is given by :
Using the property of differentiation, we get :
So, the magnitude of the acceleration of the object at time t = 2.00 s is . Hence, this is the required solution.
Before we solve this, we should know this fact:
According to Newton's Law of Gravitation, the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The force acts along the line joining the centres of the two objects. It can be shown by this:
Now, let us check all the options.
A. As we move to higher altitudes, the force of gravity on us decreases.
<em>This </em><em>statement </em><em>is </em><em>true.</em>
The force of gravity is inversely proportional to the square of distance from the centre of the earth. If, we go up the surface of the earth, the distance from the centre of the earth increases and hence the value of force of gravity decrease. So, force of gravity decreases with altitude.
B. As we move to higher altitudes, the force of gravity on us increases.
<em>This </em><em>statement</em><em> </em><em>is </em><em>false.</em>
We have already got the result in option A. that the force of gravity decreases with altitude. It never increases with altitude.
C. As we gain mass, the force of gravity on us decreases.
<em>This </em><em>statement</em><em> </em><em>is </em><em>false.</em>
The force of gravity is directly proportional to the product of the masses. So, if increase our mass, then the force of gravity will also increase and if we decrease our mass, then the force of gravity decreases.
D. As we gain mass, the force of gravity on us increases.
<em>This </em><em>statement</em><em> is</em><em> </em><em>true.</em>
As mentioned earlier in option C., the force of gravity is directly proportional to the product of the masses of the earth and another object. So, as we gain mass, the force of gravity on us increases.
E. As we move faster, the force of gravity on us increases.
<em>This </em><em>statement</em><em> is</em><em> </em><em>true</em><em>.</em>
Here, we have to consider a different formula. According to Newton's Second Law,
F = ma, where F is the force, m is the mass and a is the acceleration.
In other words,
F ∝ a, i.e., force is directly proportional to acceleration.
We know, acceleration is the rate of change of velocity of an body within a time period.
So, if speed is increased, then acceleration will also be greater, which results in the increase of force. So, as we move faster, the force of gravity on us increases.
<u>Answers:</u>
A: As we move to higher altitudes, the force of gravity on us decreases.
D: As we gain mass, the force of gravity on us increases.
