Answer:
good job my boy this is the right answer
Explanation:
The impulse (the variation of momentum of the ball) is related to the force applied by
where
is the variation of momentum, F is the intensity of the force and
is the time of application of the force.
Using F=1000 N and
, we can find the variation of momentum:
This
can be rewritten as
where
and
are the final and initial momentum. But the ball is initially at rest, so the initial momentum is zero, and
from which we find the final velocity of the ball:
If two different substances, with the same mass (1 gram) absorb the same amount of energy "the temperature of the substance with the lower specific heat will increase more than the one with a higher specific heat".
Option B
<u>Explanation:</u>
The thermodynamic function that specifies the amount of heat needed by one degree of temperature for a single unit of mass of a material to be elevated is understood as "Specific heat". Depending on the extent to which they absorb heat, various levels of specific heat values are seen for the materials.
The heat transferred relies on three factors: temperature change, weight of the device, material change and stage of the material. The average temperature of the molecules increases as the material heats up, so when they collide they are more likely to contribute enough energy to cause rotation and vibration to happen as the energy moves to a higher state.
Answer:
230 torr
Explanation:
Given that
P = 230 mm of Hg
If argon gas and mercury is in equilibrium position then the pressure on the both side will be same .
As we know that
1 torr = 1 mm of Hg
So the pressure of the argon will be 230 torr .
Unit conversion
1 torr = 1 mm of Hg
1 bar = 100 KPa = 10⁵ Pa = 10⁵ N/m² = 0.1 MPa = 0.1 x 10⁶ Pa
