In an element's square on a periodic table, the numerical value indicates the atomic mass or atomic weight of a certain element. It is also similar to the number of protons in a specific atom. Each element varies from one another. So the greatest numerical value represents the most atomic mass among elements.

serious [3.7K]

Answer:

The potential difference across a given given wire of an circuit is directly proportional to the current flowing through it provided it's temperature remains the same. This is known as ohm's law

V is proportional to I

V/I = constant

V/I = R

V = IR where R is the constant of proportionality and resistance of the wire

Hope this helps!

Keith_Richards [23]

Answer:

(a) Magnetic force $F=38.584\times 10^{-19}N$

(b) Acceleration $a=5.846\times 10^8m/sec^2$

(C) Speed will remain same

Explanation:

We have given velocity of alpha particle v = 520 m/sec

Magnetic field B = 0.034 T

Charge on alpha particle $q=3.2\times 10^{-19}C$

Mass of alpha particle $m=6.6\times 10^{-27}kg$

Angle between velocity and magnetic field 43°

(a) Force acting on the particle is equal to

$F=q(v\times B)=qvBsin\Theta$

$F=3.2\times 10^{-19}\times 320\times 0.034\times sin43^{\circ}$

$F=38.584\times 10^{-19}N$

(B) According to newton's law

F = ma. here m is mass and a is acceleration.

So acceleration

$a=\frac{F}{m}=\frac{38.584\times 10^{-19}}{6.6\times 10^{-27}}=5.846\times 10^8m/sec^2$

(c) As the magnetic force is always perpendicular to velocity so speed will remain same neither decreases nor increases.

STALIN [3.7K]

Answer:

a) the number of particles increases

b) average distance between them should decrease

c) the number of particles decreases, the pressure must also decrease

Explanation:

a) When the girl pumps to increase the pressure inside the tire she introduces more particles. Therefore the number of particles increases

b) as the volume of the tire does not change and there are more particles, the average distance between them should decrease

c) When a hole is opened, some of the particles inside the tire come out, so as the number of particles decreases, the pressure must also decrease
