Answer:
4.4 MJ
Explanation:
We are given that an automobile with an internal combustion engine converts the potential energy of gasoline into kinetic energy of the moving piston.
1 kg of gasoline gives energy=44 MJ.
Average internal combustion engine =10 % efficient
We have to find how much potential energy is converted into energy to run the pistons.
10% of 44 =
Since 10% is efficient of internal combustion.
Therefore, 4.4 MJ potential energy is converted into energy to run the pistons.
Answer:
11.6m
Explanation:
should be somewhere around 11.6 because
a²+b²=c²
so 6²+10²=136
now find the square root √136
=11.6
11.6²=136
Answer:
V = 5 Volts
Explanation:
Given the following data;
Work done = 20 Joules
Charge = 4 Coulombs
To find the potential difference;
Mathematically, the work done in moving a charge is given by the formula;
W = qv
Where;
W is the work done
q is the quantity of charge
v is the potential difference
Substituting we have;
20 = 4 * v
V = 20/4
V = 5 Volts

Spectrum Width
Answer:
The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
Explanation:
just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
