Answer:

so to find the acceleration we divide the change in velocity by the time taken for it so intial velocity was 3m/s and final velocity is 10m/s. we substract 3 from 10 to get the change in velocity ie 10m/s -3m/s = 7m/s. now decide this by the time taken for it that is 4 sec as given. acceleration is 7/4 = 1.75m/s^2

The chemical reaction causes electricity to flow through the terminals to the load attached. Some of the acid in the battery remains on the plates as it flows through. When the battery is recharged the acid is returned to the liquid solution to provide more power later.

Light in vacuum is incident on the surface of a glass slab. In the vacuum the beam makes an angle of 38.0° with the normal to th

iren [92.7K]

Answer:

n_glass = 1.404

Explanation:

In order to calculate the index of refraction of the light you use the Snell's law, which is given by the following formula:

$n_1sin\theta_1=n_2sin\theta_2$ (1)

n1: index of refraction of vacuum = 1.00

θ1: angle of the incident light respect to normal of the surface = 38.0°

n2: index of refraction of glass = ?

θ2: angle of the refracted light in the glass respect to normal = 26.0°

You solve the equation (1) for n2 and replace the values of all parameters:

$n_2=n_1\frac{sin\theta_1}{sin\theta_2}=(1.00)\frac{sin(38.0\°)}{sin(26.0\°)}\\\\n_2=1.404$

The index of refraction of the glass is 1.404

astra-53 [7]

Answer:

0.6m/s²

Explanation:

Given parameters:

Initial velocity = 3m/s

Final velocity = 4.5m/s

Time taken = 2.4s

Unknown:

Average acceleration = ?

Solution:

To solve this problem, we use the expression:

Acceleration = $\frac{v - u}{t}$

v is the final velocity

u is the initial velocity

t is the time taken

Acceleration = $\frac{4.5 - 3}{2.5}$ = 0.6m/s²
