Answer:
83000 m/s
Explanation:
Using
F = Bqv....................... Equation 1
Where F = Force experienced by the charge, B = magnetic field q = charge of the particle, v = speed of the particle.
make v the subject of the equation
v = F/Bq.................... Equation 2
Given: q = 5.2×10⁻¹⁹ Coulombs, F = 9.5×10⁻¹⁵ Newtons, B = 2.2×10⁻¹ Tesla
Substitute into equation 2
v = 9.5×10⁻¹⁵ /(5.2×10⁻¹⁹×2.2×10⁻¹)
v = 8.3×10⁴ m/s
v = 83000 m/s
Answer:
Q= 231.88 W/m²
Explanation:
Given that
L= 20 cm
K= 2.79 W/m·K
T₁=50°C
T₂= 22°C
h=15 W/m₂·K
The total thermal resistance
Now by putting the values
R= 0.138 K/W ( for heat flux A= 1 m²)
Heat flux Q= ΔT/R
Q= (50-22)/0.138 = 32/0.138 W
Q= 231.88 W/m²
The total amount of revenue collected from $1 per unit tariff on this product will be $7.
What is revenue from tariffs?
A tax rate known as a revenue tariff is one that is used to obtain direct income from company revenues. The level of prices is significantly impacted by a revenue tariff.
How do tariffs bring in money?
As imports reach the domestic market, the government will earn more money because a tariff is a tax. Since import prices are artificially inflated, domestic sectors also profit from less competition.

I understand that the question you are looking for is "The total amount of revenue collected from a $1-per-unit tariff on this product will be: $22. $14. $8. $7".
Answer:
1) move away from the windows.
When abrupt changes in pressure (produced by the hurricane) affect the windows, they can "explode" and be a serious danger for the people.
2) Go to the lowest level of the building.
Is safer than the upper levels because the lower levels suffer less from the strength of the hurricane (being closer to the ground increases the structural resistance), make sure that you have everything you may need in case of an emergency.
m = mass of the object lifted by you = 14 kg
g = acceleration due to gravity by earth on the object being lifted = 9.8 m/s²
h = height to which the object is lifted slowly = 0.80 m
W = Work done in lifting the object
work done in lifting the object is same as the gravitational potential energy gained by the object. hence
Work done = Gravitation potential energy of object
W = m g h
inserting the values
W = (14) (9.8) (0.80)
W = 109.8 J
