Which statement is true?

Physics
2 answers:
Alisiya [41]3 years ago

This is kind of an awkward situation.

A, B, and C are definitely false:

A ... gasoline is not a renewable resource

B ... hydroelectric dams don't use wind for anything; windmills do

C ... fossil fuels are not renewable resources

So that leaves D, but D is partly absurd too.

Natural gas burning does not produce gases to turn the turbines.  Natural gas is burned to produce HEAT, just like on the stove in my kitchen.  The heat is used to boil water, and the steam from the boiling water is what turns the turbines to generate electrical energy.

But I guess you gotta pick  <em>choice-D</em>  as the answer.

The answer is D. Natural gas can be burned, producing hot gases that turn turbines to generate electricity.

Answer:

the law of conservation of electric charge that states that electric charge cannot be created or destroyed, it can only be exchanged between bodies.

Explanation:

In physics there are several conservation laws that are of great importance, among them we have the law of conservation of electric charge that states that electric charge cannot be created or destroyed, it can only be exchanged between bodies.

In general, the Earth is a very large body and is considered a reservoir where the electrical charge can be stored, but cannot be destroyed.

An electron is released from rest in a uniform electric field of 418 N/C near a particle detector. The electron arrives at the d
Oksanka [162]

Answer:

a) 7.35 x 10¹³ m/s²

b) 5.03 x 10⁻⁸ sec

c) 9.3 cm

d) 6.23 x 10⁻¹⁸ J

Explanation:

E = magnitude of electric field = 418 N/C

q = magnitude of charge on electron = 1.6 x 10⁻¹⁹ C

m = mass of the electron = 9.1 x 10⁻³¹ kg

a)

acceleration of the electron is given as

a = \frac{qE}{m}

a = \frac{(1.6\times 10^{-19})(418)}{(9.1\times 10^{-31})}

a = 7.35 x 10¹³ m/s²

b)

v = final velocity of the electron = 3.70 x 10⁶ m/s

v₀ = initial velocity of the electron = 0 m/s

t = time taken

Using the equation

v = v₀ + at

3.70 x 10⁶ = 0 + (7.35 x 10¹³) t

t = 5.03 x 10⁻⁸ sec

c)

d = distance traveled by the electron

using the equation

d = v₀ t + (0.5) at²

d = (0) (5.03 x 10⁻⁸) + (0.5) (7.35 x 10¹³) (5.03 x 10⁻⁸)²

d = 0.093 m

d = 9.3 cm

d)

Kinetic energy of the electron is given as

KE = (0.5) m v²

KE = (0.5) (9.1 x 10⁻³¹) (3.70 x 10⁶)²

KE = 6.23 x 10⁻¹⁸ J

What are constellations?
tatiyna

Answer:

Option 4

Explanation:

A constellation can be defined as that region formed by the stars in such a way that the formation by the group of stars in that area appear to seem an imaginary pattern of some mythological creature, animal, god or some inanimate object formed apparently.

Thus in accordance with the above definition a constellation is a group of stars that forms some apparent pattern in the celestial sphere.
