Based on data from world energy consumption, the estimated humanity’s current consumption of energy in one day is above 208 million joules per day.
<h3>What is energy consumption?</h3>
Energy is the ability to do work. Therefore, energy consumption refers to the amount of energy used to do work.
Humans need energy for various purposes such as;
- lighting
- heating
- operation of machines
- feeding, etc.
Due to rapid growth on population as well as technology, the human energy consumption is on the increase.
In 2020, the world primary energy consumption was 71,4 GJ per person for a world population of about 7.7 billion people.
Therefore, the estimated humanity’s current consumption of energy in one day is above 208 million joules per day.

Answer:
current going into a junction in a circuit is EQUAL TO the current comming out of the junction.
Explanation:
Krichhoff's Current Law
Kirchhoff's current law (1st Law) states that current flowing into a node (or a junction) must be equal to current flowing out of it.
Answer:
The answer is C because they have to be close to be able to interact
The change in momentum of the car is 6000 kg m/s
Explanation:
According to the impulse theorem, the change in momentum of an object is equal to the impulse exerted on the object, therefore:
where
is the change in momentum
I is the impulse exerted
For the car in this problem, the impulse received is
I = 6000 kg m/s (in the forward direction)
Therefore, the change in momentum of the car is equal to this value:
(in the forward direction)
We can also calculate what is the new momentum of the car. In fact, the initial momentum is
And so, the new momentum is
