Answer: Her test trials had a high level of accuracy but a low level of precision.
Explanation:
Vapor pressure<span> or equilibrium </span>vapor pressure<span> is defined as the </span>pressure<span> exerted by a </span>vapor<span> in thermodynamic equilibrium with its condensed phases at a certain temperature. It is independent with atmospheric pressure since it does not change by changing the atmospheric pressure only. </span>
Answer:
the acceleration during the collision is: - 5
Explanation:
Using the formula:

we get:

Answer:

Explanation:
We are given that three resistors R1, R2 and R3 are connected in series.
Let
Potential difference across 
Potential difference across 
Potential difference across 
We know that in series combination
Potential difference ,
Using the formula

Hence, this is required expression for potential difference.
Answer:550N
Explanation:
mass=1100kg
Acceleration=0.5m/s^2
Force=mass x acceleration
Force=1100 x 0.5
Force=550N
