Atomic mass unit (amu)

That's going to depend on exactly what you want to measure about the particles. If it's the particle's mass then the unit is related to the kilogram. If your measuring the size of the particle then you will use a unit related to the meter. If you want to measure the age of the particle then you'll use a unit related to the second.

An electron in an electron gun is accelerated from rest by a potential of 25 kV applied over a distance of 1 cm.
podryga [215]

Answer:

9.38\times 10^7 m/s

Explanation:

We are given that

Potential ,V=25 kV=25\times 10^3 V

Distance,r =1 cm=\frac{1}{100}=0.01 m

1 m=100 cm

Mass of electron, m=9.1\times 10^{-31} kg

Charge, q=1.6\times 10^{-19} C

We have to find the final velocity of the electron.

Speed of electron,v=\sqrt{\frac{2qV}{m}}

Using the formula

v=\sqrt{\frac{2\times 1.6\times 10^{-19}\times 25\times 10^3}{9.1\times 10^{-31}}

v=9.38\times 10^7 m/s

Hence, the final velocity of the electron=9.38\times 10^7 m/s

The Surface Pressure at Leh, Ladakh is 800 mb. Now, assuming that Leh is at an altitude of 3500 m and every 100 m increase in he
Basile [38]

We have that the sea level pressure for Leh area is 1150mb mathematically given as

Ps= 1150 mb

<h3> Sea level pressure</h3>

Question Parameters:

Ladakh is 800 mb.

<u>assuming </u>that Leh is at an altitude of 3500 m and every 100 m

increase in height with respect to sea level corresponds to 10 mb pressure,

Generally, for 3500m the pressure change will be 350 mb.

Therefore,  here for the sea level <em>pressure</em> we need to add,

Ps=800+350

Ps= 1150 mb

A.5 kg model rocket launches with a thrust of 5 n in the upward direction. can it lift off of the ground? (hint: gravity is pull
Sphinxa [80]

Answer:

F = F2 - F1     where F is the net force upwards

F = 5 - (.5 * 9.8) = (5 - 4.9) N = .1 N

Since there is a net force in the upwards direction the rocket should experience an upwards acceleration.
