1. What is wave motion

Physics
1 answer:
nadya68 [22]2 years ago
8 0
A wave is basically propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

A bus accelerates to 60 m/s to the east in 10 s. What is the buses acceleration? 2. A car traveling at 10.0 m/s to the west acce
professor190 [17]

Answers:

1) a=6\frac{m}{s^{2}}

2) t=8s

Explanation:

1) Acceleration a is defined as the variation of Velocity V in time t :  

a=\frac{V}{t}  (1)

A body also has acceleration when it changes its direction.

In this case we have a bus with a velocity of 60m/s to the east, that accelerates in a time 10s. So, we have to find the bus's acceleration:

a=\frac{60m/s}{10s}  (2)

a=6m/s^{2}  (3)  This is the bus's accelerration

2) Now we have a car that accelerates 2m/s^{2}  to the west in order to reach a speed of 16m/s in the same direction, and we have to find the time t it takes to the car to reach that velocity.

Therefore we have to find  t from (1):

t=\frac{V}{a}  (4)

t=\frac{16m/s}{2m/s^{2}}  (5)

Finally:

t=8s  (6)

The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasin
Ganezh [65]

Answer:

The current in the circuit decrease slowly .

Explanation:

Given as :

For the electrical circuit

The voltage V in the circuit is slowly decreasing

The resistance R of the resistor slowly increasing after heating

Now, From Ohm's Law

Voltage is directly proportional to the flow of current through circuit

I.e V ∝ I

Or. V = R × I

where R is the proportionate constant and this is the resistance of the resistor

whose property is to opposes the flow of current in the circuit

So, If R value more then current I reduces in the circuit

∵ Here in the circuit ,  The resistance is slowly increasing, so, current I is slowly decreasing .

Hence The current in the circuit decrease slowly . answer

Why do you see colors when you look at reflected light from a cd
Nady [450]
The colors that you see on the CD are created by white light reflecting from ridges in the metal. When light reflects off or passes through something with many small ridges or scratches, you often get rainbow colors and interesting patterns. They are called interference patterns.
