Because it can pollute the air and cause wild life to eat stuff that has been contimanted by the air
To help you out I'll give you the equations a) s=d ÷t
b) a=vf-vi ÷ t
Answer:
10.2 m
Explanation:
The position of the dark fringes (destructive interference) formed on a distant screen in the interference pattern produced by diffraction from a single slit are given by the formula:
where
y is the position of the m-th minimum
m is the order of the minimum
D is the distance of the screen from the slit
d is the width of the slit
is the wavelength of the light used
In this problem we have:
is the wavelength of the light
is the width of the slit
m = 13 is the order of the minimum
is the distance of the 13th dark fringe from the central maximum
Solving for D, we find the distance of the screen from the slit:
Compression is a type of force, like when you crush a soda can, your compressing it.
Answer:
88 Watts
Explanation:
From the question given above, the following data were obtained:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = IV....... (1)
From ohm's law,
V = IR ........ (2)
Substitute the value of V in equation (2) into equation (1)
P = IV
V = IR
P = I(IR)
P = I²R
With the above formula (i.e P = I²R), we can obtain the power lost to heat as follow:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = I²R
P = 20² × 0.22
P = 400 × 0.22
P = 88 Watts
Thus, the power lost to heat is 88 Watts.
