Answer:

Explanation:

convection is like when the bubble forming at the bottom of a pot of water rise and the cool water falls to the bottom and then heat up and rise to the top and so on which is why the pot heats mostly evenly.

While playing catch with my dog I bounced the ball off the ground at a 30-degree angle. It had a range of 6 meters.

The initial velocity of the ball is 8.2 m/s

Explanation:

The motion of the ball is a projectile motion, which consists of two separate motions:

- A uniform motion along the horizontal direction, at constant velocity

- A uniformly accelerated motion along the vertical direction, with constant acceleration ( $g=9.8 m/s^2$ , acceleration of gravity)

The range of a projectile can be derived by the equation of motions along the two directions, and it is found to be:

$d=\frac{v^2 sin 2\theta}{g}$

where

v is the initial velocity of the projectile

$\theta$ is the angle of projection

g is the acceleration of gravity

For the ball in this problem, we have

$\theta=30^{\circ}$

d = 6 m is the range

Solving for v, we find the initial velocity:

$v=\sqrt{\frac{gd}{sin 2\theta}}=\sqrt{\frac{(9.8)(6)}{sin (2\cdot 30^{\circ})}}=8.2 m/s$

3) A small, 30 gram pith ball carrying 3 nC of charge is dangling from an insulating string. Another charged pith ball carrying

ludmilkaskok [199]

Answer:

q2 = 5.1μC

Explanation:

From a forces diagram we can stablish that:

Fe = T*sin(16) (eq1)

T*cos(16) = m*g (eq2)

Where Fe is the electric force and T is the tension of the string. Solving for Fe:

Fe = m*g*tan(16)

The magnitude of the electric force is calculated as:

$Fe = \frac{K*q1*q2}{d^2} = m*g*tan(16)$ Solving for q2:

$q2 = \frac{m*g*tan(16)*d^2}{K*q1}=5.1 \mu C$
