c. Developing new technologies designed to see farther into space
than before
What is universe?The universe is everything including all of space, and all the matter and energy that space contains. Also it includes time itself and, of course, it includes us.
What began as a sequence one-upmanship in space-related technological advancements between the U.S. and the Soviet Union would spawn incredible progress observed in innovation to this day. The battle for dominance not only as a global superpower, but a space power, led the United States and the Soviet Union to race to put men in space and eventually on the moon.
The launch of the Soviet satellite Sputnik on Oct. 4, 1957, would place pressure on the U.S. to design technologies crafted for space exploration. This, in turn, spurred a series of innovations in technology that would have far reaching impacts beyond space.
These technologies can be seen as developments in modern healthcare, construction, and transportation. Relevant examples include medical imaging techniques, artificial limbs, water filtration systems, solar panels, firefighting equipment, shock absorbers, air purifiers, home insulation, weather resistant airplanes, infrared thermometers, and countless other vital inventions.
While all these creations help sustain essential aspects of modern life, we carry one of the largest technological advancements from the space race in our pockets today.
Therefore, Developing new technologies designed to see farther into space than before lead scientists to develop new explanations about the universe.

What is the difference between catastrophism and uniformitarianism
Explanation:
Catastrophism is a geological concept or ideology that was formerly in place. It suggests that the earth crust has evolved through only drastic and violent geological events.
Uniformitarianism suggests that the earth carefully evolved over a period of time and that the processes that are occurring today have occurred in times past.
Catastrophism presents a drastic and rapid evolution of the crust. Uniformitarianism takes a gradual approach to events and suggests that we can use the present to unravel the past.Roller coasters accelerates from initial speed of 6.0 M/S2 final speed of 70 M/S over four seconds. What is the acceleration?
Answer:
[tex]a=16\ m/s^2[/tex]
Explanation:
Motion With Constant Acceleration
It's a type of motion in which the velocity of an object changes uniformly in time.
The formula to calculate the change of velocities is:
[tex]v_f=v_o+at[/tex]
Where:
a = acceleration
vo = initial speed
vf = final speed
t = time
The roller coaster moves from vo=6 m/s to vf=70 m/s in t=4 seconds. To calculate the acceleration, solve for a:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
[tex]\displaystyle a=\frac{70-6}{4}=\frac{64}{4}[/tex]
[tex]\boxed{a=16\ m/s^2}[/tex]

Which is a possible result of rising ocean temperatures caused by global warming?
formation of dust bowls
increase in strength of hurricanes
rapid evaporation of water in soil
decrease in population due to health threats
Answer:
Increase in strength of hurricanes
Explanation:
A possible result of rising ocean temperatures caused by global warming is increase in strength of hurricanes.
What is global warming?Global warming is an environmental concern characterized by the gradual increase in the Earth's atmospheric temperature.
Global warming can lead to the rise of temperature in air and oceans as well.
One consequence of an increase in ocean temperature is that the strength of hurricanes, which is strong wind accompanied by rain, will be increased.
Therefore, a possible result of rising ocean temperatures caused by global warming is increase in strength of hurricanes.

Please I need help with this question (see image).
Show workings where necessary.
Answer:
Solution:
i) Heat supplied by heater = Heat gained by water = m * c*theta = 0.12Kg * 4200 * 10 = 5040Joules in 2 minutes.
ii) Power = Energy/time = 5040J/(2 * 60seconds) = 5040J/120seconds = 42Watts.
(iii) Heat supplied to the 70g of water = m * c * theta = 0.07Kg * 4200 * 9K = 2646J
(iv) Heat supplied by heater = Heat gained by 70g of water + Heat supplied to the metal vessel.
But,from our calculations above,
Heat supplied by heater = 5040J ......and
Heat supplied to the 70g of water = 2646J
.: substituting the values,we have that :
5040J = 2646J + Heat supplied to the metal vessel.
5040J - 2646J = Heat supplied to the metal vessel.
.: Heat supplied to the metal vessel = 2394J.
(v) Heat gained by metal vessel = Heat capacity of the vessel * theta.
2394J = Heat capacity of the vessel * 9K
.: Heat capacity of the vessel = 2394/9 = 266(Joule per Kelvin)
(vi) Using the formula:
Heat Capacity = mass * specific heat capacity
.: Specific heat capacity = Heat Capacity/mass = 266/0.55 = 484(Joules per Kilogram per Kelvin)

What is the kinetic energy of a jogger with a mass of 65.0 kg traveling at a speed of 2.5m/s
Answer:
203.1J
Explanation:
Given parameters:
Mass = 65kg
Speed = 2.5m/s
Unknown:
Kinetic energy of jogger = ?
Solution:
To solve this problem, we use the kinetic energy equation:
K.E = [tex]\frac{1}{2}[/tex] m v²
m is the mass
v is the velocity
Now insert the parameters and solve;
K.E = [tex]\frac{1}{2}[/tex] x 65 x 2.5² = 203.1J
