I think the gravitational attraction would increase for the object with higher mass
Answer:
Intensity
Explanation:
The intensity of a sound wave is equal to the ratio between to the power emitted by the source divided by the area of the spherical surface through which the wave propagates:
where
P is the power
is the area of the spherical surface
r is the distance from the source
As we see from the formula, the intensity is inversely proportional to the square of the distance from the source:
so, intensity is the correct answer.
Answer with Explanation:
We are given that
Current,I=12 A
V=11.5 V
I'=9 A
Internal resistance,r=0.05 ohm
a.We have to find the emf of battery.
Using the formula
b.Voltage of ligh
Hence, the current through the starting motor when the light areon=61 A
Answer
given,
mass of the shell = 87 g = 0.087 Kg
speed of the muzzle = 853 m/s
mass of the helicopter = 4410 kg
A burst of 176 shell fired in 2.93 s
resulting average force = ?
momentum of the shell = m v
= 0.087 x 853
= 74.21 kgm/s
momentum of 176 shell is = 176 p
= 176 x 74.21
= 13060.96
momentum of helicopter = - 13060.96 kgm/s
amount of speed reduce a =
a=
a = 2.96 m/s²
velocity = \dfrac{2.96}{2.93}
v = 1.01 m/s
You should include any source you used to obtain the information.
