What is the resistance of a 3.5 m copper wire (Rho= 1.7x10-8 Ohm·m) that 1 point

VikaD [51]

Answer:

(D)

Explanation:

Given :

l=3.5 m

$A=5.26*10^{-6}$ $m^{2}$

$p=1.7*10^{-8} ohm.m$

Resistance can be calculated as :

$R=p\frac{l}{A} \\R=1.7*10^{-8} \frac{3.5}{5.26*10^{-6} }$

$R=\frac{5.95*10^{-2} }{5.26} \\R=1.13*10^{-2}$

Resistance of the wire will be 1.1× $10^{-2}$ ohms

Option D is correct

What is the kinetic energy of a 7.26 kg bowling ball that is rolling at a speed of 2m/s

vlada-n [284]

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

$k = \frac{1}{2} m {v}^{2} \\$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2} \times 7.26 \times {2}^{2} \\ = 2 \times 7.26$

We have the final answer as

Hope this helps you

A bicycle has a momentum of 36 kg* m/s and a very!I city of 4 m/s.What is the mass of the bicycle?

Strike441 [17]

p = 36 kgm/s

v = 4m/s

we know that,

p = mv

so,

$m = \frac{p}{v}$

$m = \frac{36}{4}$

$m = 9kg$

Any object that is given any initial velocity and which follows a path due to gravitational force acting on it and by the frictional resistance of the atmosphere is called a projectile. This is because the object is projected and not influenced by anything except gravity.
