Answer:
A
Explanation:
C = (F-32)*5/9 = 73*5/9 = 40.55555
since the answers are spread apart, technically you can just estimate by doing -32
and then /2
since 5/9 is close to 1/2
Answer:
528.9 nm
Explanation:
For a grating dsinθ = mλ where m = order of grating, d = grating space, λ = wavelength of light and θ = angle of deflection of light
First, we find the grating space d = mλ/sinθ where m = 2 for second order, λ = 632.8 nm = 632.8 × 10⁻⁹ m, θ = 43.2°
d = mλ/sinθ = 2 × 632.8 × 10⁻⁹ m ÷ sin43.2° = 1.849 × 10⁻⁶ m = 1.849 μm
We now find the wavelength of the light to be measured from λ = dsinθ/m
Here, θ = 34.9° and m = 2 for second order. So, we have
λ = dsinθ/m = 1.849 × 10⁻⁶ m × sin34.9° ÷ 2 = 0.5289 × 10⁻⁶ m = 528.9 nm
The force is perpendicular to the plane formed by v and B. Since the force is zero if v is parallel to B, charged particles often follow magnetic field lines rather than cross them.
B) F = |q|vBsin

Answer: 7.74 newtons</h3>
========================================
Steps Shown:
Work = Force*Displacement
Power = Work/Time
Power = (Force*Displacement)/Time
900 W = (F*1000 m)/(8.6 sec)
900 = (F*1000)/8.6
900*8.6 = 1000F
7740 = 1000F
1000F = 7740
F = 7740/1000
F = 7.74 newtons
Answer:
Fluid pressure from gravity is the weight of the fluid above divided by the area it is pushing on. Fluid pressure applies in all directions. Internal pressure of an object equals the external fluid pressure, otherwise the object could be crushed. Wind and heating can also create pressure.
