Answer:
Speed of the car around the circular path will be 12 m/sec
Explanation:
We have given mass of the car m = 1500 kg
Radius of the curve r = 45 m
Centripetal acceleration of the car
We have to find the speed of the car
We know that centripetal acceleration is given by , here v is car speed along the circular path and r is radius of the curve
So
v = 12 m/sec
So speed of the car around the circular path will be 12 m/sec
Answer:
They have the same current.
Explanation:
According to the Ohm's Law, resistors in series have the same current, distinct potential differences and resistances. The case for n resistors in series are:

Answer:
Explanation:
given,
speed of the pebble = 14 m/s
height of the building = 31 m
ignoring air resistance
a) horizontally
V_x = 14 m/s
time =
time =
times = 2.52 s
v_y = 9.8 x 2.52
v_y = 24.7 m/s
resultant velocity
=
= 28.39 m/s
b) vertically straight up
max height =
=
= 11.47 m
height covered = 31 + 11.47
= 42.47 m
velocity =
=
= 28.85 m/s
c) vertically down
v² = u² + 2as
v² = 2 × 9.8 × 31 +14²
v² = 803.6
v = 28.35 m/s
