E=mcθ
where E is the energy added,m is the mass,c is the specfic heat capacity and θ is the change in temprature.
making m subject u get E/c<span>θ=m
</span><span>θ=(30-20)=10</span><span>
plugging the values we get :

<span>
solving it we get the answer that is 0.25kg or 250 grams

Answer:
Explanation:
Since the universal SI unit for velocity is meters/second, let's convert ft/s to m/s:
We can use the following kinematics equation to solve this question:
What we know:
- The initial velocity,
, is 
- (physics concept) The final velocity must be equal in magnitude but opposite in direction to the initial velocity (
) - Acceleration,
, is acceleration due to gravity at about 
Solving for 
:
An example of body language would be rolling your eyes. That's saying that you're bored, don't care, stop talking to other people without even opening your mouth.
Answer:
The angular speed of the Crab nebula pulsar is 190.3 rad/s.
Explanation:
Given that,
Time T= 33 ms = 0.033 s
The angular speed is equal to the 2π divided by time period.
We need to calculate the angular speed of the Crab nebula pulsar
Using formula of angular speed
Where, T = time
= angular speed
Put the value into the formula
Hence, The angular speed of the Crab nebula pulsar is 190.3 rad/s.
