Answer:

Explanation:

This question is showing a stoichiometric reaction.  But the out put is Helium and nitrogen.     while the input has Hydrogen and something else.  Hydrogen doesn't turn into different elements.  So I think the question is wrong.   But, He is missing , and so is the nitrogen, but since that's not a choice, maybe they hope you'll put  He   ??   :/  But like I said , the question is just wrong.

The electric potential difference of a 150 µF capacitor is measured across the terminals of the capacitor and found to be 5 volt
Lapatulllka [165]
The potential energy stored in a capacitor is given by:
U= \frac{1}{2}CV^2
where
C is the capacitance of the capacitor
V is the potential difference across the plates of the capacitor

In our problem,
C=150 \mu F= 150 \cdot 10^{-6} F
V=5 V
Therefore, the potential energy of the capacitor is
U= \frac{1}{2}(150 \cdot 10^{-6}F)(5 V)^2 = 1.88 \cdot 10^{-3}J

The Hoover dam is a hydroelectric power plant that converts the energy of falling water into electricity. Which of the following
vlabodo [156]

The correct answer to the question is : B) The weight of the water, and C) The height of the water.

EXPLANATION :

Before coming into any conclusion, first we have to understand potential energy of a body.

The potential energy of a body due to its position from ground is known as gravitational potential energy.

The gravitational potential energy is calculated as -

                      Potential energy P.E = mgh

 Here, m is the mass of the body, and g is the acceleration due to gravity.

h stands for the height of the body from the ground.

We know that weight of a body is equal to the product of mass with acceleration due to gravity.

Hence, weight W = mg

Hence, potential energy is written as P.E = weight × height.

Hence, potential energy depends on the weight and height of the water.

The velocity time graph of an object is shown below. How far does the object travel in the time interval t =4 s to t = 6 s?
Trava [24]

The distance covered by the object between t =4 s and t = 6 s is 4 m

Explanation:

In a velocity-time graph, the distance covered by the object represented can be found by calculating the area under the curve.

Therefore, the distance covered by the object between t = 4 s and t = 6 s is the area under the curve between 4 s and 6 s.

We see that we have to calculate the area of a triangle, with:

Base:

b=6-4 = 2

And height:

h=4-0 = 4

Therefore, the area is

A=\frac{1}{2}bh=\frac{1}{2}(2)(4)=4

So, the distance covered by the object is 4 m.
