What causes the wind to blow

Air at the equator is warmed by the direct rays of the sun while air at the poles is cooled because the suns rays are not so direct. As air warms, it expands and becomes less dense therefore rises, similarly but vice versa for cool air.

Hope this helped

Ohm’s Law pls answer this photos

Rudiy27

Answer:

Trial 1: 2 Volts, 0 %

Trial 2: 2.8 Volts, 0%

Trial 3: 4 Volts, 0 %

Explanation:

Th experimental values are given in the table, while the theoretical value can be found by using Ohm/s Law:

V = IR

TRIAL 1:

V = IR

V = (0.1 A)(20 Ω)

V = 2 volts

% Difference = $|\frac{Theoretical Value - Exprimental Value}{Theoretical Value}|$ x 100%

% Difference = |(2 - 2)/2| x 100%

% Difference = 0 %

TRIAL 2:

V = IR

V = (0.14 A)(20 Ω)

V = 2.8 volts

% Difference = $|\frac{Theoretical Value - Exprimental Value}{Theoretical Value}|$ x 100%

% Difference = |(2.8 - 2.8)/2.8| x 100%

% Difference = 0 %

TRIAL 3:

V = IR

V = (0.2 A)(20 Ω)

V = 4 volts

% Difference = $|\frac{Theoretical Value - Exprimental Value}{Theoretical Value}|$ x 100%

% Difference = |(4 - 4)/4| x 100%

% Difference = 0 %

A rock is thrown from the edge of the top of a 51 m tall building at some unknown angle above the horizontal. The rock strikes t

Xelga [282]

Answer:

The speed of projection is 34 m/s.

Explanation:

Height of building, h = 51 m

horizontal distance, d = 74 m

time, t = 8 s

Let the angle is A and the speed is u.

d = u cos A x t

74 = u cos A x 8

u cos A = 9.25 .... (1)

Use second equation of motion

$h = u sin A t - 0.5 gt^2\\\\-51 = u sinA \times 8 - 0.5\times 9.8\times8\times 8\\\\u sin A = 32.8 .... (2)$

Squaring and adding both the equations

$u^2 = 9.25^2 + 32.8^2 \\\\u = 34 m/s$

Complete Question

Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?

Answer:

The time it would take at the given speed is $x = 43.00 \ minutes$

Explanation:

From the question we are told that

The time taken to exist the highway is $t = 55 min$

The distance to the exist is $d = 43\ mi$

Alberta speed is $v = 60 mph$

The time it would take travelling at the given speed is mathematically represented as

$t_z = \frac{d}{v}$

substituting values

$t_z = \frac{43}{60}$

$t_z = 0.71667\ hrs$

Converting to minutes

1 hour = 60 minutes

So 0.71667 hours = x minutes

Therefore

$x = 0.71667 * 60$

$x = 43.00 \ minutes$
