When we describe electric flux, we say that a surface is oriented in a certain direction with respect to an electric field. When

stepladder [879]

Answer:

2. Dot Product

Explanation:

The calculation of the electric flux gives an scalar result.

When we tray to calculate how much electric field passes trough a surface, we are calculating a scalar value. Furthermore, the concept of flux requires the calculation of a scalar value.

Also it is necessary to take into account that the magnitude of the flux trough a surface depends of the inclination of the surface respect to the direction of the electric field. This is taken into account sufficiently by a dot product.

Then, the answer is:

2. Dot Product

A stone is dropped from the edge of a roof. find the distance travelled by the stone in 2sec after its release.

Lena [83]

S = ?
U = 0
V = ?
A = 9.81
T = 2

we tryna find s

lets use s = ut + (at^2)/2
ut cancels out since u = 0
(at^2)/2 = (9.81 x 2^2)/2
= 19.62m

How do you think that changing the mass of the pendulum bob will affect the period of the pendulum swing?

myrzilka [38]

(Mass does not affect the pendulum's swing. The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)

if a ball is thrown horizontally from the first floor of a building (5.0 m from the ground) at a speed of 5.0 m/s, where will it

r-ruslan [8.4K]

The ball will be 49.5m from the base when it hits the ground based on 9.8m/s² earth gravity.

what is earth gravity?
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

Why do things fall down when you throw them or drop them? The answer is because gravity ; an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.

First, let's try to find the time taken by ball to reach the ground :

$-h = 0 - \frac{1}{2}gt^{2}$

t = $\sqrt{2gh}$

t = $\sqrt{2*9.8*5$

t = 9.9 s (rounded)

Next, we will find the horizontal distance covered by ball :
D = v*t
D = 5 * 9.9

D = 49.5m

Therefore, the ball will be 49.5m from the base when it hits the ground for the first time based on 9.8m/s² earth gravity.
