From the question, the given charge moving within the magnetic field would have a value of 1.82 x [tex]10^{-7}[/tex] C.
A charge is either a positively or negatively charged particle. When a charge is moving through a magnetic field, it would experience a force which depends on the amount of the charge, its speed, the magnetic field strength and angle. The force on a charge in a magnetic field can be determined by:
F = qvBSin θ
where: q is the charge, v is its velocity/ speed in the field and θ is the angle of deflection of the charge.
Given that: F = 7.89 x [tex]10^{-7}[/tex] N, v = 2090 m/s, B = 4.23 x [tex]10^{-3}[/tex] T and θ = 29.4°.
Thus, the amount of the charge can be determined by;
q = [tex]\frac{F}{vBsin O}[/tex]
= [tex]\frac{7.89*10^{-7} }{2090*4.23*10^{-3}* Sin 29.4 }[/tex]
= [tex]\frac{7.89*10^{-7} }{4.340}[/tex]
q = 1.818 x [tex]10^{-7}[/tex]
q = 1.82 x [tex]10^{-7}[/tex] C
Therefore, the amount of the charge that moved within the magnetic field is 1.82 x [tex]10^{-7}[/tex] C.

What mass of water in grams will fill a tank 100cm long, 50cm wide, 30cm high?
Answer:
150,000grams
Explanation:
100*50*30=150,000
Also 1ml water= 1 grams
Answer:
150,000³
Process:
You multiply 100cm x 50cm x 30cm. The reason you do this is because the "mass" will be the volume of the tank of water. A "small 2" would represent a two dimensional area, whereas the "small 3" would represent a 3 dimensional area.

Answer:
the thumb
Explanation:
pressure is exerted more by an area of small surface area.
pressure is got by P=Force/Area in contact
on the thumb there is a smaller area in contact. so as the area reduces, the force exertes becomes greater.
A box is 300 kg & it covers the area of 150 m2 find the pressure exerted by the box in the ground.
Answer:
If we assume that the box is a cube with 150 m² surface area
Area of 1 face = 150 m² / 6 = 25 m²
The box will exert a downward force of
Force = mass * acceleration due to gravity
Force = 300 kg * 9.81 m/s² N
Force = 2943 N
The box exerts a pressure ( force / unit area) = 2943 N / 25 m²
Pressure = 117.7 N/m²

What's Centripetal force................
Answer:
a force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.
Answer:
A centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path.

a) A car accelerates uniformly at 3.7 m s⁻² as it passes a stationary road train. The initial speed of the car is 30 m s⁻¹, and it reaches the speed limit of 130 km h⁻¹ as it passes the front of the cab. Calculate the length of the road train. Give your answer to 3 significant figures. include units in your answer.
b) The braking distance of a road train travelling at 15 m s⁻¹ is 70 m. Assuming that the same deceleration is applied at all speeds, calculate the braking distance of a road train travelling at 25 m s⁻¹
(a) The length of the train is 54.6 m
(b) The braking distance of the road train is 194.44 m
The given parameters:
acceleration of the car, a = 3.7 m/s²
initial velocity of the car, u = 30 m/s
final velocity of the car, v = 130 km/h = 36.11 m/s
To find:
the length of the trainThe length of the train is the distance travelled by the car
The distance traveled by the car is calculated as:
[tex]v^2 = u^2 + 2as\\\\2as = v^2 - u^2\\\\s = \frac{ v^2 - u^2}{2a} \\\\where;\\\\s \ is \ the \ distance \ travelled \ by \ the \ car\\\\s = \frac{(36.11)^2 - (30)^2}{2\times 3.7} \\\\s = 54.585 \ m\\\\s \approx 54.6 \ m[/tex]
Thus, the length of the train is 54.6 m
(b) The braking distance of a road train travelling at 25 m s⁻¹
[tex]a = \frac{v_1^2}{2s_1} = \frac{v_2^2}{2s_2} \\\\Given;\\\\s_1 = 70 \ m\\\\v_1 = 15 \ m/s\\\\v_2 = 25 \ m/s\\\\s_2 = ?\\\\2s_2v_1^2 = 2s_1v_2^2\\\\s_2 = \frac{ 2s_1v_2^2}{2v_1^2} \\\\s_2 = \frac{s_1v_2^2}{v_1^2} \\\\s_2 = \frac{70\times 25^2}{15^2} \\\\s_2 = 194.44 \ m[/tex]
Thus, the braking distance of the road train is 194.44 m

Answer:
In plotting position versus time it can be seen that the green line represents a fixed position at the various times given - the other lines represent changing position with time
The (horizontal) green line describes an object that's not moving.
Whatever TIME you pick to look at the green line, its POSITION is always the same. This is a pretty good description of "not moving".
The other three lines all have different positions at different times, so they all describe motion.

Answer:
Explanation:
Tides occur in the ocean but nit in lakes because an ocean is a free flowing body of water that can travel a large area of the globe while a lake or pond only covers a small area of the earth so it is not affected by gravity as violently and in turn, prevents the formation of tides.
