Force, according to Newton's second law of motion, is calculated through the equation,
F = m x a
where F is force, m is mass, and a is acceleration.
We are already given with the mass of 103 kg, we therefore need to solve for the acceleration.
acceleration = (13.9 m/s - 1.4 m/s) / 1 s = 12.5 m/s²
Then, we substitute this value to the equation above.
F = (103 kg) x (12.5 m/s²)
F = 1287.5 N
Thus, the force involved in the collision is approximately 1287.5 N.

Answer:
Explanation:
Given
Mass of water is
mass of ice is
Latent heat of fusion
The heat capacity of water is
Suppose water is at and it reaches to to melt the ice
the heat released by water must be equivalent to heat absorbed by the ice
Answer:
The ratio of the pressure at the top to the pressure at the bottom is
Explanation:
Given that,
Number of molecules
Mass
Temperature = 300 K
Height
We need to calculate the ratio of the pressure at the top to the pressure at the bottom
Using barometric formula
Where, m = mass
g = acceleration due to gravity
h = height
k = Boltzmann constant
T = temperature
Put the value in to the formula
Hence, The ratio of the pressure at the top to the pressure at the bottom is
Answer: 28
Explanation:
Given
Circuit breaker current is
Power of the light bulb is
Voltage of the DC-circuit is
If the resistance are connected in parallel, they must have same voltage i.e. 120 V
So, Resistance is given by
For the 20 A current and 120 V battery, net resistance is
Suppose there are n resistance in the circuit connected in parallel.
Thus, there can maximum of 28 bulbs.
