Answer:
Electron will travel to a distance of 0.189 m before its velocity is 0
Explanation:
We have initial speed of the electron
Electric field
Charge on electron will be
Mass of electron
We know that Columbus force is equal to F = qE and according to newtons law force is equal to F = ma , here m is mass and a is acceleration
These two forces will be equal
So ma = qE
According to third equation of motion
So
s = 0.189 m
So electron will travel to a distance of 0.189 m before its velocity is 0
Answer:
a). Maximum Length L=0.929m
b). T=0.83 Hz or 1.2s
c). Longer, the effortless waling T=2.1 Hz or t=0.475s
d). t=1.2s V=0.774
t=0.475s V=1.95
Explanation:
Length legs=L=1.1m
angle=50
the step that give the person forms a triangle whose two sides are known and the angle that forms between them, then using trigonometry as the image
Divide the original triangle in two and form a right triangle so the angle is 25 and the L is hypotenuse and the opposite is the step length
a).
Length of the step
L=0.464m*2
L=0.928m
b).
period=T
c).
The period is the inverse of the time of the motion so, the T1 is faster that the T because
d).
The speed is the relation between the distance with time so:
Answer:
Explanation:
m = Mass of water = 2 kg
c = Specific heat of water =
= Change in temperature =
Change in thermal energy is given by
Cale's change in thermal energy was .
Explanation:
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
