Answer:
Explanation:
The gravitational potential energy of an object is the energy possessed by the object due to its location in the gravitational field.
This energy is always measured as a difference with respect a "zero level" - generally taken as the ground level.
Therefore, it generally makes more sense to measure the change in gravitational potential energy of an object when its height is changed; this is given by:
where:
m is the mass of the object
is the acceleration due to gravity
is the change in height of the object
<span>Yes, there are! r1 and r2 are numbers. The volume of the hollow shell is 4 π 3 ( r 3 1 − r 3 2 ) 4π3(r13−r23). Now multiply by ρ to get the mass.</span>
Answer:
The power in this flow is
Explanation:
Given that,
Distance = 221 m
Power output = 680 MW
Height =150 m
Average flow rate = 650 m³/s
Suppose we need to calculate the power in this flow in watt
We need to calculate the pressure
Using formula of pressure
Where, = density
h = height
g = acceleration due to gravity
Put the value into the formula
We need to calculate the power
Using formula of power
Put the value into the formula
Hence, The power in this flow is
Answer: Money is indivisible and Credit cards are used primarily to withdraw money from a checking account are two false statements.
Explanation:
Since we know the characteristics of money as follows:
1) Money is divisible.
2) Money has different forms - coins, notes, demand deposits, cheques, tokens, funds in checkable deposits etc.
3) Money is a unit of account.
4) Money is measure of value.
5) Money is store of value.
So, Money is indivisible is false.
And credit cards are used primarily to withdraw money from a checking account is false , as debit cards are used for withdrawing money.
Hence, Money is indivisible and Credit cards are used primarily to withdraw money from a checking account are two false statements.
(a) The amplitude of the wave is 3 cm.
(b) The speed of the wave is 19.6 m/s
(c) The angular frequency is 653.72 rad/s.
(d) The period of the wave is 0.0096 s.
(e) The wavelength of the wave is 0.392 m.
<h3>
Speed of the wave</h3>
The speed of the wave is calculated as follows;
where;
- μ is mass per unit length = (0.26 kg)/(2 m) = 0.13 kg/m
- T is tension
<h3>Angular frequency</h3>
ω = v/r
ω = v/A
ω = 19.6/0.03
ω = 653.72 rad/s
<h3>Period of the wave</h3>
<h3>Wavelength</h3>
v = fλ
λ = v/f
λ = 19.6/50
λ = 0.392 m
