Explanation:
Given:
Δy = d
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2(g)(d)
v = √(2gd)
If we double d:
√(2g (2d))
√(4gd)
Compared to the first velocity:
√(4gd) / √(2gd)
√2
So the new velocity is √2 greater than the first velocity.
√2 v
I think the answer is Fossils formed gradually over time.
The total thrust, expressed in pounds or tons, that the hydraulic-feed mechanism on a drill can impose on a drill string; also, the pressure of the fluid within the hydraulic cylinders, generally expressed in pounds per square inch. Ref: Long.
Hydraulic pressure is the force imparted per unit area of a liquid on the surfaces which it has contact. Liquids are incompressible, and as such, when a load acts
The maximum energy that can be transferred by the electrical generator is 2.7×10¹³ Joules.
We can use the equation of electric power and electric energy.
Electric Power: This can be defined as the ratio of the electric energy to the time of electrical equipment.
⇒ Formula
- P = E/t............... Equation 1
⇒Where:
- P = Maximum electric power
- E = Maximum electric Energy
- t = time.
make E the subject of the equation
- E = Pt................. Equation 2
From the question,
⇒ Given:
- P = 1.5×10⁹ W
- t = 5 hours = (5×60×60) seconds = 18000 seconds = 1.8×10⁴ s
⇒ Substitute these values into equation 2
- E = (1.5×10⁹)(1.8×10⁴)
- E = 2.7×10¹³ Joules.
Hence, the maximum energy that can be transferred by the electrical generator is 2.7×10¹³ Joules.
