A path that allows only one route for an electric current is called a Series circuit. A series circuit is circuit that's arranged in a chain making it to where there's only one path to take
Answer:
v = 21.52 m/s
Explanation:
Given that,
The distance covered by the car, d = 6200 km
Time taken by the car, t = 80 hours
We need to find the speed of the car. The speed of an object is given by total distance dividing total time.
So, the speed of the car is 21.52 m/s.
Answer: 1.33
Explanation:
We would apply Snell's law which is expressed as
niSinθi = nrSinθr
where
θi = angle of incidence
θr = angle of refraction
ni = index of refraction of the incident medium(air)
nr = index of refraction of the refractive medium(liquid in this case)
From the information given,
ni = 1(index for air)
θi = 37
θr = 27
By substituting these values into the formula, we have
1 * sin37 = nr * sin27
nr = sin37/sin27
nr = 1.33
The index of the liquid is 1.33
Answer:
Explanation:
Given
Volume of bucket
Time taken to fill the bucket
so volume flow rate is
1 gal is equivalent to
mass flow rate
(b)Average velocity through nozzle exit
As we can see that the boy is moving his hand up and down while producing the wave in the string.
Here we can see that the source of disturbance or source of wave here in this example is the boy who is holding the string at one end.
So here the motion of the hand of boy is representing the motion of medium molecules in the medium always
So here the disturbance of wave is travelling in the string to the right direction while if we see the direction of medium molecules then it is moving perpendicular to the string i.e. up and down
This type of wave is known as transverse waves in which medium molecules moves perpendicular to the direction of wave
