Answer:
Answer 1) Decomposing (Electrolysis) Answer 2) Solar energy
Explanation:
Answer 1) Decomposing (Electrolysis)
Explanation :
Hydrogen can be created by decomposing water. Electrolysis which is a method of passing electricity from the water and obtaining the products as hydrogen and oxygen is done by decomposition of water. The water molecule is broken down into its constituents.
Answer 2) Solar energy
Explanation :
If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is Solar energy.
Solar energy from the sun can be used to lower the energy of activation during the decomposition of water. Solar energy is a renewable energy source as it comes from the sun and is replenish-able unlike fuels which cannot be replenished. The solar energy can be collected and utilized for production of hydrogen.

Paul needs to randomly select one of his four children to go first in a board game. which simulation tools could he use in this situation?
The simulation tools that could be used by Paul in this situation is :
A spinner divided evenly into 12 sections, with three sections each of four different colors A standard deck of cards. Two coinsDescription of the simulator toolsA spinner divided into 12 sections with three sections each having four different colors can be used by calculating the prob of each subsection which simulates the probability of picking one of four children
Probability of each subsection
= number subsection / number of section
= 3 / 12 = 1/4
Two coins can also simulate the picking of one of four children
The outcome of the two coins = ( HH, HT, TT, TH )
Therefore the probability of picking a H or T
= 1 / 4
Also deck of 52 cards can also simulate the probability of picking one out of four children to go first in a board game.
Hence we can conclude that the simulator tools that can be used are A spinner divided evenly into 12 sections, with three sections each of four different colors A standard deck of cards. and Two coins.

To avoid an accident, a driver with a mass of 60 kg applies his brakes and decelerates from 30 m/s to 1 m/s in 2 seconds. how much force was absorbed by his seat belt?
When brakes are applied, force absorbed by his seat belt was 870 N.
What is force?The force is an action of push or pull in order to move or stop the body.
Given is the mass m=60 kg, velocity changes from v1 =30m/s to v2= 1m/s in time t=2s.
The acceleration is the time rate of change of velocity.
a = v1 -v2 /t
a =30 -1 /2
a = 14.5 m/s²
According to the Newton's second law of motion, the force absorbed by belt was
F =ma
F =60 x 14.5
F = 870 N.
Thus, force absorbed by his seat belt was 870 N.

Two football players with mass 80 kg and 120 kg run directly toward each other with speeds of 8 m/s and 10 m/s respectively. if they grab each other as they collide, the combined speed of the two players just after the collision would be
The combined speed after the collision is -2.8 m/s.
How to get the combined speed?
Here we must have conservation of momentum, where momentum is the product between mass and velocity.
At the beginning, one of the players has a mass of 80kg and a velocity of 8m/s, so its momentum is:
P₁ = 80kg*(8m/s) = 640 kg*m/s
The other player has a mass of 120 kg and runs in the opposite direction at a speed of -10m/s (the negative sign is because of the direction). So its momentum is:
P₂ = 120kg*(-10m/s) = -1200 kg*m/s
The initial total momentum is:
P = P₁ + P₂ = 640 kg*m/s + ( -1200 kg*m/s) = -560 kg*m/s
At the end, the move together as a mass of (80kg + 120kg) = 200kg with a velocity V.
Such that the final total momentum is equal to the initial total momentum.
So we must have:
200kg*V = -560 kg*m/s
V = (-560 kg*m/s)/200kg = -2.8 m/s.
The combined speed after the collision is -2.8 m/s.

Of 1000 students surveyed, 490 were boys and 320 had bicycles. of those who had bicycles, 130 were girls. what is the probability that a student surveyed was either a boy or had a bicycle?
By definition of probability, the probability that a student surveyed was either a boy or had a bicycle is 62%.
Definition of ProbabitityProbability is the greater or lesser possibility that a certain event will occur.
In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.
Events and probability in this caseIn first place, let's define the following events:
A: The event that a student surveyed was a boy.B: The event that a student surveyed had a bicycle.Then you know:
P(A)= [tex]\frac{490}{1000}[/tex]=0.49= 49%P(B)= [tex]\frac{320}{1000}[/tex]= 0.32= 32%P(A and B)= P(A∩B)= [tex]\frac{190}{1000}[/tex]= 0.19= 19% [320 students had bicycles. Of those who had bicycles, 130 were girls. Then, 190 were boys.]In this case, considering the definition of union of eventes, the probability that a student surveyed was either a boy or had a bicycle is calculated as:
P(A∪B)= P(A) + P(B) -P(A∩B)
P(A∪B)= 0.49 + 0.32 -0.19
P(A∪B)= 0.62= 62%
Then, the probability that a student surveyed was either a boy or had a bicycle is 62%.
