Answer:
velocity of the car is 7.3516 m/s
Explanation:
M1v1a + m2v1b = m1v2a + m2v2b
775*30 + 1475*0 = 775*v2a+1475*11.9
Let v2a be x
23250 + 0 = 775x + 17552.5
775x = 23250-17552.5
775x = 5697.5
X = 7.3516 m/s
Answer:
The switch within the closed circuit is opened and it stops the flow of current in a circuit.
Explanation:
- Current is defined as a flow of electrons in a system or a circuit.
- There are two basic things needed for current to flow in a system
- One is the electro-motive force and the other is the complete path for current to flow.
- If a switch in a closed circuit gets opened, it restricts the path of current flow.
- Thus it stops the current to be flowed through the circuit.
The answer is C.
I just took the test!
Hope this helps. :)
Answer:
y and length is directly relation
Explanation:
Given data
A single-slit diffraction pattern is formed on a distant scree
angles involved = small
to find out
what factor will the width of the central bright spot on the screen change
solution
we know that for single slit screen formula is
mass ƛ /area = sin θ and y/L = sinθ
so we can say mass ƛ /area = y/L
and y = mass length ƛ / area .................1
in equation 1 here we can see y and length is directly relation so we can say from equation 1 that the width of the central bright spot on the screen change if the distance from the slit to the screen is doubled
