F = m × g
Now when, a force acts on the object at an angle and in downwards, thus formula becomes:
= N = mg + F sin(x)
Here,
- N = normal force, m = mass , g = acceleration due to gravity, F = outside force, x = the angle formed
See, as we habe to calculate the weight, which is m × g, thus we will recreate thus formula like thus:
= N = w + F sin(x) --------- [Weight = w]
Now, the solutions becomes easy from here, just put the values:
= N = w + F sin(x)
= 200 = w + 90 × sin(32)
= 200 = w + 90 × 0.55
= 200 = w + 49.5
= 200 - 49.5 = w
= 150.5 = w
I have got my answer but in approx, hope you will not mind. ^^"
Answer:
The order of maximum is 
Explanation:
From the question we are told that
The diffraction grating is k = 300 lines per mm = 300000 lines per m
The wavelength is 
Generally the condition for constructive interference is mathematically represented as
Here n is the order maximum
d is the distance the grating which is mathematically represented as
=> 
=> 
So
at maximum 
=> 
=>
Answer:
11.7 m
Explanation:
I assume north is the y direction and x is the east direction, so Δx refers to the displacement in the east direction.
First, find the time it takes for the velocity to change from directly north to directly east.
Given (in the y direction):
v₀ = 2.88 m/s
v = 0 m/s
a = 0.350 m/s² sin(-52.0°) = -0.276 m/s²
Find: t
v = at + v₀
(0 m/s) = (-0.276 m/s²) t + (2.88 m/s)
t = 10.4 s
Given (in the x direction):
v₀ = 0 m/s
a = 0.350 m/s² cos(-52.0°) = 0.215 m/s²
t = 10.4 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (0 m/s) (10.4 s) + ½ (0.215 m/s²) (10.4 s)²
Δx = 11.7 m
The changes in celsius are the same as those in kelvins. the difference between the two scales is that 0 celsius is about 273 kelvins and that 0 kelvins is about -273 celsius (note the minus sign)
