Fist you would put them in order and then cross one off from each side so like 4kg and 13kg and the last two that you have you would add the 4kg and the 6kg and divide by 2 to get the aswer of 5kg.
4kg+6kg=10kg
10kg/2kg=5kg
Thus, the car would travel a distance of 50 metres in 4 seconds.
Answer:
restoring force is 2 N
Explanation:
given data
angle pulled = 5°
force = 1 N
pulled = 10°
to find out
restoring force
solution
we know here force
force = m×g×sinθ ..........1
so here θ is very small so sinθ = θ
1 = mg(5)
mg = 1 /5 ..................2
and
now for 10 degree
we know here θ is small so sinθ = θ
so from equation 1
force = m×g×sinθ
put equation 2 here
force = 1/5 × 10
force = 2 N
so restoring force is 2 N
Answer:
1. e m fmax = 0.00598 Volt
2. Imax = 0.000854 Amp
Explanation:
1. Find the maximum induced emf.
e m fmax =
Given that e m fmax = N*A*B*w
N = 1
A = 2 cm^2 = 0.0002 m^2
f = 143 rotation per minute = 143/min
f = (143/min) * (1 min/60 sec) = 2.38/sec
w = 2Πf = 2 * Π * 2.38 = 14.95 rad/sec
B = 2T
e m fmax = N*A*B*w
e m fmax = 1 * 0.0002 * 2 * 14.95
e m fmax = 0.00598 Volt.
2. Find the maximum current through the bulb.
Imax = e m fmax / R
Where R is the total resistance in the circuit is 7 Ω.
Imax = 0.00598/7 = 0.000854 Amp.
Imax = 0.000854 Amp
Answer:
v = 14.87 m/s
Explanation:
Given that
Initial speed ,u= 9.2 m/s
θ = 4°
Distance d= 100 m
Lets speed after traveling 100 m is v.
From the diagram
h = d sinθ
h = 100 sin 4°
h = 6.97 m
We know that
v = 14.87 m/s
