Given:
g =? m/s2
m = 2.2 kg
w = 19.6 N
Equation: g = w/m
g = 19.6 N/2.2 kg
<span>g = 8.9 m/s2</span>
Answer:
f=15.5 Hz
Explanation:
Let's determine the internal resistance:
ρ = 1.68*10^-8 Ω m
Ω
Since the bulb is rated at 12.0 V and 25.0 W,
Current
Therefore, voltage drop inside generator =
Actual EMF required is
Note that this is an RMS value.
The peak voltage is
For a generator, by Faraday's Law,
*ω
ω
f=ω/(2π)=
f=144.5 rad/s/(2π)
f=23.001 Hz
S=d/t
30/0.75=40
Answer: 40km/h
Answer:
Part a)
Part b)
Explanation:
As we know that the electric field between the membrane is given as
here the distance between two membranes is given as
now we know that potential difference between two membranes is given as
so we have
Part b)
Kinetic energy of helium nucleus is given as
so we have
Answer:Spot B
Explanation:
Mary will Reject spot B which can be explained by the process of Selective thinking.
Selective reasoning is the practice in which one chooses favorable memory and concentration information while ignoring unfavorable proof of belief.
This kind of reasoning is the foundation of most beliefs in so-called mind readers and media's psychic powers. It is also the basis of many, though not all, mysticism and pseudo science beliefs.
though hotels are modern but the presence of very cold water and strong winds might become the factors to reject spot B
