Her estimate would not be greater, so it would be near the actual estimate. the numbers 70 and 10 are smaller than the numbers 73 and 12, so it is not possible for 70 x 10 to be more than 73 x 12 is. i hope this helps!!
Answer:
Yes, Venus does not have the same magnetic field as that of earth's
Explanation:
Instead, there are solar wind particles that can deeply penetrate the venus atmosphere and can collide with the other carbon atoms already present in the air but lacks oxygen and thus does not have that strong magnetic field which would deflect the suns rays and create aurora in the sky at night.
Answer:
(a): The cyclist is behind the car.
(b): The speed of the car are Vf= 31.97 m/s.
Explanation:
f= 440 Hz
f'= 415 Hz
Vo= 1/3 Vf
Vf= ?
V= 343.2 m/s
f'= f* ( (V-(-Vo) / (V-(-Vf) )
clearing Vf
:
Vf= 31.97 m/s
Vo= 10.65 m/s
Hi there!
Converting from angular velocity to tangential velocity can be done by:
v = ωr
v = tangential velocity (m/s)
ω = angular velocity (rad/sec)
r = radius (m)
Convert 12 cm to meters:
100 cm = 1 m
12 cm = 0.12 m
Now, convert rev/min to rad/sec:
v = 20.94 · 0.12 = 2.51 m/s
Answer:
0.076 kg
Explanation:
The force created by gravity can be found using mass x (9.8 m/s^2).
mg=0.750 N
m(9.8) = 0.750
Multiply both sides by 9.8: m = 0.076 kg
