A train is moving with the velocity of 10m/s . It attains an acceleration of 4m/s after 5 sec . find the distance covered by train at that time.

Answers

Jdndbxndbsjanwndnfbdbdjdjd

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

Answers

(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 train

The 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

A charge feels a 7.89 x 10-7 N force when it moves 2090 m/s at a 29.4° angle to a 4.23 x 10-3 T magnetic field. What is the amount of the charge?

Answers

We have that the amount of the charge q is

[tex]q=1.8*10^{-7}[/tex]

From the Question we are told that

Force [tex]F=7.89 x*10^{-7}[/tex]

Velocity [tex]V=2090m/s[/tex]

Angle [tex]\theta=29.4[/tex]

Magnetic field [tex]B=4.23 * 10^{-3} T[/tex]

Generally, the equation for Force F is mathematically given by

[tex]F=qVBsin\theta\\\\q=\frac{F}{VBsin\theta}[/tex]

[tex]q=\frac{7.89 x*10^{-7}}{4.23 * 10^{-3} T*sin29.4*2090m/s}[/tex]

[tex]q=1.8*10^{-7}[/tex]

In conclusion

The amount of the charge q is

[tex]q=1.8*10^{-7}[/tex]

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.

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.

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.
