The scientist is likely to be studying kinematics.
Kinematics is the branch of science, specifically physics, which is concerned with the motion of objects without reference to the forces that induce this motion. An example of kinematics is studying the change in velocity of an object over time or the distance covered by an object in a specified amount of time.
Answer:
Temperature at which the resistance is twice the resistance at 
is 
Solution:
As per the question:
Temperature coefficient, 
Reference temperature, 
Resistance, 
Now, using the formula:
- Yes, this temperature holds for all all the conductors of copper, irrespective of the size and shape of the conductor.
Answer:
Force of 
Kgm/s^2 must be applied to the piston to raise oil to a height of 6.0 m
Explanation:
As we know,
Pressure is the force per unit area
Or 
Force 
Pressure is the product of density, gravitational constant and height
Force
Kgm/s^2
If you are given time and distance, you can determine power if you know
force. watts. energy. joules.
Answer is joules.
Power is defined as the rate of
doing work. Hence power = work / time then you obtain watts. Work is the
product of force and displacement (distance). Hence in formula, w = F x s. In
which the S.I unit of work is joule in the product. This is what you have to
obtain in order to calculate for power.
Answer:
P and S waves slow down when they reach this layer. The asthenosphere, also known as the magma chamber, is the uppermost component of the mantle. This layer is partially molten and is a ductile zone in a tectonically poor state.
It's almost hard and seismic waves move through the asthenosphere at a slow rate. The fragile lithosphere and the uppermost portion of the asthenosphere are assumed to be rigid.
seismic waves travel more quickly through denser materials and therefore generally travel more quickly with the depth it moves more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.
