Determine the acceleration due to gravity?

1 answer:

8 0

That's a weird graph, but judging from the units the acceleration is the slope of the graph.

a = (0.8 - 0.3)/(0.16 - 0.055) = 4.76 m/s²

What’s the resistance in the circuit

inna [77]

Answer:

I = 0.75 A

Explanation:

The question is not to calculate the resistance, but to calculate the current. (The resistance is already given by the value of 2 Ohm).

U = I * R

I = U / R

with U = 1.5 V and R = 2 Ohm

I = 1.5 / 2

I = 0.75 A

Answer:

11.85m

Explanation:

For the development of this problem we must resort to the concepts of the basic kinematic equations that define the distance of a body, such as speed for a certain time, that is,

$D=v*t$

From the information provided we say that the distance between the cretas is 0.6m,

$D_{crest} = 0.6m$

In our information we have also that the length between the first and latest wave is in time terms of 2.2s. They are 4 waves in 3 intervals then

$D_{T} = D_{crest}*3= 0.6*4 = 2.4m$

$t=1.6s$

$\upsilon = \frac{D_{T}}{t} = \frac{2.4}{1.6}$

$\upsilon = 1.5 m/s$

Then the distance from the shore is given by the speed of the waves for the total time. That is

$X = \upsilon*T\’$

$X = 1.5*7.9$

$X= 11.85m$
