Answer:
The position after 3 minutes is - 800 m.
Explanation:
speed, v = 100 m/s
time, t = 3min = 180 s
initial position, x = 1000 m
let the distance traveled in 3 minutes is d
d = 100 x 180 = - 18000 m
So, the position is
= - 18000 + 1000 = - 800 m

Answer:
Magnetic field, B = 0.016 Tesla
Explanation:
It is given that,
Velocity of electron, v=9.6\times 10^5\ m/sv=9.6×10
5
m/s
Magnetic force, F=2.6\times 10^{-15}\ NF=2.6×10
−15
N
Charge, q=1.6\times 10^{-19}\ Nq=1.6×10
−19
N
The magnetic force is given by :
F=qvBF=qvB
B=\dfrac{F}{qv}B=
qv
F
B=\dfrac{2.6\times 10^{-15}}{1.6\times 10^{-19}\times 9.6\times 10^5}B=

B=0.016\ TB=0.016 T
So, the magnitude of magnetic field is 0.016 Tesla. Hence, this is the required solution.
Answer:
30 N
Explanation:
there are two forces act on the bar:
- weight of 1.5 kg mass, w = mg = 15 N
- weight of the bar, wb
for balance,
w * Lw = wb * Lwb
Lw = length of bar from the mass to the pivot
Lwb = lenght of bar from the center of the bar to the pivot
15 * 20 = wb * (50-20)
300 = wb * 30
wb = 300/30 = 30 N
Its d. the water isn't moving the fish, and that's how they remain stationary. they don't have any currents pushing on them. if this is wrong, its c, which is practically the same thing. but its most likely d.
Answer:
The three "accelerators" are: the throttle, the steering wheel and the brakes.
Explanation:
Acceleration means change in velocity. But this change may be in module or in direction.
Car throttle will increase the velocity module of the car and brakes wil diminish it. On the other hand, the steering wheel will change the direction of the velocity.
Hope my answer helps you. Have a nive day!
