Which of the following is an instantaneous speed?
Brilliant_brown [7]

Answer:

A: All of the above

Explanation:

The instantaneous speed of an object is simply the current seed of the object at any given time. The SI unit is m/S and it is a vector quantity.

Therefore, according to the given options, they all have SI units that are consistent with distance and time which makes them all an example of instantaneous speed.

a particle with a charge of 5.5 x 10^-8 c is 3.5 cm from a particle with a charge of -2.3 x10^-8 c. the potential energy of this
Yuri [45]

Answer:

-32.5 * 10^-5 J

Explanation:

The potential energy of this system of charges is;

Ue = kq1q2/r

Where;

k is the Coulumb's constant

q1 and q2 are the magnitudes of the charges

r is the distance of separation between the charges

Substituting values;

Ue = 9.0×10^9 N⋅m2/C2 * 5.5 x 10^-8 C *( -2.3 x10^-8) C/(3.5 * 10^-2)

Ue= -32.5 * 10^-5 J

Physics in motion Unit 6A The nature of waves
Daniel [21]

#1

length of one complete wave shape is known as wavelength

#2

Frequency is defined as number of oscillations per second or number of waves passing through a point in one second.

#3

One Time period is the time to cover one complete wavelength distance by the wave

#4

relation between time period and frequency is given as

f = \frac{1}{T}

#5

Time period of simple pendulum is given as

T = 2\pi \sqrt{\frac{L}{g}}

so it depends on length of pendulum and acceleration due to gravity

#6

amplitude of the wave is the height above the axis to which particle can attain its maximum position or its maximum height on y axis is amplitude
