Answer:
P = n P₀ 4.9 10¹⁴ Pa
Explanation:
The radiation pressure for full absorption is
P = S / c
Where S the pointing vector, which is equal to the intensity of the beam that is defined as the energy per unit area per unit time
The energy of the protons can be calculated
Em = K = ½ m v²
Area
A = π r²
Intensity is
I = n ½ m v² / π r²
I = ½ n m /π v² / r²
We replace
S = U / t A
S = ½ n m /π v² / r² Δt
The pressure is
P = 1/c (½ n m /π (v / r Δt)²2
Δt = 45 10⁻⁹ s
P = n [½ m /πc (v/r)²] 4.9 10¹⁴
The amount in square brackets is the pressure that a proton creates, which is why it is useful
P = n P₀ 4.9 10¹⁴ Pa
Where Po is the pressure created by a proton
Answer:
Speed of the car after the collision is 1.2 m/s
Explanation:
It is given that,
Mass of first car, m₁ = 2 kg
Velocity of first car, v₁ = 6 m/s
Mass of second car, m₂ = 3 kg
Velocity of second car, v₂ = -2 m/s (it is travelling in opposite direction)
The two cars lock together and move along the road. This shows an inelastic collision. Let their common velocity is V. On applying the conservation of momentum as :
V = 1.2 m/s
So, after collision the speed of the cars is 1.2 m/s. Hence, this is the required solution.
In a series circuit, there's only one path for current, so the current
for each bulb has to go through all of them.
If one bulb stops shining ... either because it burned out, or because
somebody unscrewed it and ran away with it ... then no current can flow
through the place where that bulb used to be, and they ALL go out.
This is the main reason why the lights in your house are NOT in series.
There are a lot of other reasons.
Answer:
You're supposed to measure the distance from X to the end of vector 5 using the appropriate scale, and measure the angle (counterclockwise from X) using a protractor.
Mathematically:
x = [83cos90+55cos141+69cos229+41cos281+61co... cm = -27 cm
y = [83sin90+55sin141+69sin229+41sin281+61si... cm = 55 cm
so d = √(x² + y²) = 61 cm
and Θ = arctan(55/-27) = -64º +180º (to get into QII) = 116º
