The change in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500
<h3>What is kinetic energy?</h3>
Kinetic energy is the energy of a body due to its motion.
To calculate the increase in the kinetic energy of the monster truck, we use the formula below.
Formula:
- ΔK.E = m(v²-u²)/2............. Equation 1
Where:
- ΔK.E = Increase in kinetic energy of the monster truck
- m = mass of the monster truck
- v = final velocity of the monster truck
- u = initial velocity of the monster truck.
From the question,
Given:
- m = 5000 kg
- v = 18 m/s
- u = 11 m/s.
Substitute these values into equation 1
- ΔK.E = 5000(18²-11²)/2
- ΔK.E = 2500(324-121)
- ΔK.E = 2500(203
- ΔK.E = 507500 J
Hence, The increase in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500.

0.000006kgm/s
Explanation:
Given parameters:
Mass = 0.01g
Velocity = 0.6m/s
Unknown:
Momentum = ?
Solution:
The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .
Momentum = mass x velocity
The unit is in kgm/s
We need to convert the mass to kilograms:
1000g = 1kg
0.01g = x kg ; 0.00001kg
Input the parameter:
Momentum = 0.00001 x 0.6 = 0.000006kgm/s

The apparent change is the Doppler shift
Let the Blaise runs for time "t" to complete the race
so the total distance he moved is given by
Now Issac runs for time t = "t - 2*60"
because it took rest for 2 minutes
now it is given that Blaise wins by 10 m distance
now the distance moved by Blaise is given by
Answer:
Explanation:
Velocity of a wave is describe as
velocity =Frequency × Wavelength
Mathematically
v = fλ
Hence, Frequency, F = v / λ
Wavelength λ = v/f
So, if the frequency is kept constant, wavelength of the wave becomes directly proportional to velocity of the wave.
And this implies that, as the speed double, the wavelength is double.
