Answer:
force makes an object move
<span>The answer 0.00140 kiloliters
</span><span>ecause one litre=100 centiliters, and one kilolitre=one litre which means that one kilolitre =100000 centiliters So 140 centiliters are 140 divided by 100000 kiloliters=0.00140 kiloliters</span>
Answer:
C) directed toward the center of the circle.
Explanation:
An object undergoing uniform circular motion is an object that is moving at constant speed along a circular trajectory.
According to Newton's Laws, in order to keep the object in circular motion, there must be a net force that keeps changing the object's direction (otherwise, the object would just move in a straight path due to its inertia).
This force is called centripetal force, and it always points towards the centre of the circular path. Its magnitude is given by
where
m is the mass of the object
v is the speed
r is the distance of the object from the centre of the trajectory
C.
1,0,-2
you solve by substitution
x=1
y=0
z= -2
Answer:
7ev
Explanation:
The Energy of an incident light is given as E = hf;
Where h is Planks constant
f is frequency
Also.
E = Eo + K.E
Where Eo is work function and K.E is kinetic energy.
Hence substituting the given values,
E = 3ev + 2ev = 5ev
The frequency of the incident wave if it's doubled the Energy would be doubled since E is proportional to f with other elements been constant.
Hence :E = 10ev
But K.E = E -Eo
= 10ev - 3ev = 7ev
Maximum Kinetic Energy is 7ev.
