The diver on the diving board is 10 meters high and has a mass of 0.050kg, what is his GPE?
sveta [45]

Answer:

<h2>4.9 J</h2>

Explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

GPE = 10 × 9.8 × 0.05

We have the final answer as

<h3>4.9 J</h3>

Hope this helps you

Two wires, each of length 1.3 m, are stretched between two fixed supports. On wire A there is a second-harmonic standing wave wh
UNO [17]

Answer:

Explanation:

Given

Length of each wire L=1.3\ m

On wire A second harmonic frequency is given by

f_2_{a}=2\times (\frac{v}{2L})

where f=frequency

v=velocity of wave

L=length of wire

v_a=f_2\times L

v_a=640\times 1.3=832\ m/s

For wire B third harmonic is given by

f_3_{b}=3\times (\frac{v}{2L})

v_b=\frac{2L}{3}\cdot f_3_{b}

v_b=\frac{2\times 1.3}{3}\times 640=554.66\ m/s

The velocity versus time graph of particle A is tangent to the velocity versus time graph for particle B at point O. What is the
lara [203]
As velocities are tangent, the value of both Particle A and Particle B would be same for that point O (Intersecting point)

a = v / t
Here, v = 7, t = 6
So, a = 7/6
a = 1.17 
As the graph is decreasing, value of acceleration would be negative.
So, a = -1.17 m/s²

In short, Your Answer would be Option C

Hope this helps!
