Acceleration

Explanation:

In the Velocity-Time graph Velocity is taken in Y-Axis and plotted against Time in X-Axis.
The unit of velocity is mentioned in m/s and unit of time is mentioned in seconds.
Here we can analyze the instantaneous acceleration and displacement covered.
From the slope we can get the body accelerated.
From the area under the graph we can get the displacement traveled.
We can calculate both average and Instantaneous acceleration from the slope of this graph.

In a double-slit experiment, light from two monochromatic light sources passes through the same double slit. The light from the

Dmitrij [34]

Answer:

$\lambda_2 = 573.3 nm$

Explanation:

As we know that the position of maximum intensity on the screen is given as

$y = \frac{N\lambda L}{d}$

here we know that

$\lambda$ = wavelength

L = distance of the screen

d = distance between two slits

now we know that the position of 8th maximum intensity is same as that of 9th maximum on the screen

so we have

$\frac{N_1\lambda_1 L}{d} = \frac{N_2 \lambda_2 L}{d}$

so here we have

$8 (645 nm) = 9 \lambda_2$

$\lambda_2 = 573.3 nm$

A typical student listening attentively to a physics lecture has a heat output of 100 w . how much heat energy does a class of 1

nexus9112 [7]

Since each student emits 100 W, so 170 students will emit:

total heat = 100 W * 170 = 17,000 W

Convert minutes to seconds:

time = 50 min * (60 s / min) = 3000 s

The energy is therefore:

E = 17,000 W * 3000 s

We cab calculate work because we know the force and distance.what else would we need to know to calculate power

san4es73 [151]

We would need to know how long it took to do the work.

Power = (work) / (time).

What type of circuit is illustrated?

Debora [2.8K]

Answer:

Parallel circuit

Explanation:

A parallel circuit is a closed circuit in which current flows and divide in two or more paths and recombining to complete the circuit, each load (light bulb) receives the fully voltage of the batteries in the circuit.
