Kinetic Energy = 1/2xmassx(velocity)^2
Input values;
K.E=1/2x7kgx(4m/s)^2
K.E.=56J
Answer: liquids take the shape of the container they are in, but have definite volume. like liquids the shape of a gas changes with the container. unlike liquids the volume of a gas changes depending on the container it is in
Explanation:
As we know by the formula of bulk modulus

now we can rearrange it as


now the final volume after pressure is applied is given as

now we know that



now plug in all data


so volume is above after pressure is applied over it
Answer:
C.Step-Down
Explanation:
Given that
Number of turn in the primary N₁= 1000
Secondary current I₂= 600 mA
Secondary voltage V₂= 8 V
Primary voltage V₁= 400 V
From the above information we can say that output voltage is low compare to input voltage.
V₂ < V₁
We know that if
1 . V₂ < V₁ - Then transformer will be step down .
2. V₂ > V₁ - Then transfer will be step up .
Here
V₂ < V₁ ( 8 V < 400 V)
So the transformer is step down transformer.
