Answer:
Explanation:
The torque applied by a force can be calculated as
where
F is the magnitude of the force
d is the length of the arm
is the angle between the direction of the force and the arm
In this problem, we have
F = 15 N
d = 2.0 m
Substituting into the equation, we find
Answer:
Distance travelled is 7 meters and the displacement is 3 meters
Answer:
Given: mass 1200kg
initial velocity: 4m/s
finial velocity: 10 m/s
time 3 sec
then
speed; initial velocity + final velocity/2
4+10/3
: 4.66m/s2
The higher the solar activity, and the hotter it is, the more the oceans heat up and water evaporates into the atmosphere. High amounts of water vapor causes things like hurricanes. However, oceans have a high absorption rate of heat so they can absorb a lot of it without heating up the atmosphere, which is pretty good or else the Earth would overheat.
Answer:
a)
b)
c)
d)
e)
Explanation:
Given that
d = 2 cm
V = 200 V
We know that
F = E q
F = m a
E = V/d
So
m a = q .V/d b
---------1
The mass of electron
The charge on electron
Now by putting the all values in equation 1
We know that
a)
s = 0.1 cm
b)
s = 0.5 cm
c)
s = 1 cm
d)
s = 1.5 cm
e)
s = 2 cm
