Answer:
It turns out that an object's kinetic energy increases as the square of its speed
Explanation:
A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph.
basiclly the faster the more impact it has when it suddenly stops or hit somthing
Answer:
Are very small.
Explanation:
Scientists use models to study atoms because atoms are extremely small and can't even be seen.
Answer:
Explanation:
It is given that,
The number of lines per unit length, N = 900 slits per cm
Distance between the formed pattern and the grating, l = 2.3 m
n the first-order spectrum, maxima for two different wavelengths are separated on the screen by 2.98 mm,
Let d is the slit width of the grating,
For the first wavelength, the position of maxima is given by :
For the other wavelength, the position of maxima is given by :
So,
or
So, the difference between these wavelengths is 14.3 nm. Hence, this is the required solution.
Answer:
velocity = 472 m/s
velocity = 52.4 m/s
Explanation:
given data
steady rate = 0.750 m³/s
diameter = 4.50 cm
solution
we use here flow rate formula that is
flow rate = Area × velocity .............1
0.750 = × (4.50×)² × velocity
solve it we get
velocity = 472 m/s
and
when it 3 time diameter
put valuer in equation 1
0.750 = × 3 × (4.50×)² × velocity
velocity = 52.4 m/s
The current flows out of the junction will be Ten Ampere.
To find the answer, we have to know about the Kirchoff's Current Law (KCL).
<h3>
What is Kirchoff's Current Law (KCL)?</h3>
- KCL states that, in any electrical network, the algebraic sum of currents meeting at a junction will be equal to zero.
- We can say that the incoming current flow will be equal to the outgoing current flow.
- In the question it is given that two wires meet at a junction with 4A and 6A currents, merging into one wire and going out.
- Thus, the total incoming current will be 4+6=10A, and as per KCL which is same as the outgoing current.
Thus, we can conclude that the current flows out of the junction will be Ten Ampere.
