Answer: D

Explanation: Resistance of current in a wire is directly proportional to the length of the wire and inversely proportional to the cross - sectional area of the wire. That is,

R = (rho × L)/A

Where

L = length of the wire

A = cross sectional Area of the wire

rho = resistivity = proportionality constant which depends on the quality of the wire.

Therefore, Resistance and resistivity are related by a:

proportionality constant dependent on the identity of the material.

A storm 10.0 km in diameter has wind speeds of 10.0 m/s. What is its angular velocity in radians per second

Aloiza [94]

Answer:

The value is $w= 2*10^{-3} \ rad/s$

Explanation:

From the question we are told that

The diameter of the storm is $d = 10.0 \ km = 10 000 \ m$

The wind speed is $v = 10.0 \ m/s$

Generally the radius is mathematically represented as

$r = \frac{d}{2}$

=> $r = \frac{10000}{2}$

=> $r = 5000 \ m$

Generally the angular velocity is mathematically represented as

$w= \frac{v}{r}$

=> $w= \frac{10}{5000}$

=> $w= 2*10^{-3} \ rad/s$

Calculate the speed of a car that travels 250 miles in 4.0 hours. (remember your unit)

MrRa [10]

250/4= 62.5 mph

to find the mph of a car, you need to divide the number of miles traveled by the hours that it took to travel that many miles
