Answer:
A kilowatt (kW) is 1000 watts. A watt-hour (Wh) is a unit that measures the amount of electrical energy used over a period of time. A kilowatt hour (kWh) is 1000 watt-hours. A kilowatt is a unit of energy that carries a lot of significance in everyday life — it's the base unit used in the routine measurement for electrical energy. All the appliances and gadgets in your home consume electricity measured in kilowatts.

Answer:
-1.0778×10⁻¹⁰ N/C
Explanation:
Applying,
E = kq/r²................ equation 1
Where E = elctric field, q = charge, r = distance, k = coulomb's law
From the question,
Given: q = -3.0×10 C, r = 5.0 m
Constant: k = 8.98×10⁹ Nm²/C²
Substitute these values in equation 1
E = (-3.0×10)(8.98×10⁹)/5²
E = -1.0778×10⁻¹⁰ N/C
Hence the electric field on the x-axis is -1.0778×10⁻¹⁰ N/C
Considering the given evidences for Alfred Wegener’s theory of continental drift;
- Scientists find fossils of species in the Arctic that typically lived in warmer areas is a form of climatic evidence
- Scientists spot fossils on different continents that look similar and prove to be the same age is a form of biological evidence
- Scientists observe that some mountain ranges on different continents tend to look alike is a form of geological evidence
<h3>What is Alfred Wegener’s theory of continental drift?</h3>
Alfred Wegener’s theory of continental drift is the theory that the whole continents were once one supercontinent which as a result of geological activities broke up into the different continents which then drifted apart.
Considering the given evidences for Alfred Wegener’s theory of continental drift;
- Scientists find fossils of species in the Arctic that typically lived in warmer areas: It is a form of climatic evidence
- Scientists spot fossils on different continents that look similar and prove to be the same age: It is a form of biological evidence
- Scientists observe that some mountain ranges on different continents tend to look alike: It is a form of geological evidence
In conclusion, Alfred Wegener’s theory of continental drift describes how the continents of today were formed.

Answer:
The force exerted on the rock by the eruption is, D. 902.5 N
Explanation:
Given data,
The mass of the rock ejected by the volcano, m = 95 kg
The acceleration of the ejected rock, a 9.5 m/s²
The force acting on an object is defined as the product of the mass and its acceleration. It is given by the relation,
F = m x a
= 95 x 9.5
= 902.5 N
Hence, the force exerted on the rock by the eruption is, F = 902.5 N
Answer:
C
Explanation:
The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei. As such it is responsible for the underlying stability of matter.
