In a parallel connection, the equivalent resistance is the summation of the inverse of each individual resistances. It is mathematically expressed as 1/ Req = 1/10 +1/20 + 1/25 = 5.263 ohms. Also, the voltage across each resistor is equal to the input voltage, therefore I = 100 / 10 = 10 Amps. I hope this helped you.
Answer:
Average force = 3.5 kN
Explanation:
Given:
Mass of Jennifer (m) = 50 kg
Initial velocity = 35 m/s
Time taken to stop body = 0.5 s
Find:
Average force
Computation:
v = u + at
0 = 35 + a(0.5)
Acceleration (a) = - 70 m/s² = 70 m/s²
Average force = ma
Average force = (50(70)
Average force = 3500 N
Average force = 3.5 kN
Space telescopes must be placed in orbit around earth in order to observe short-wavelength radiation.
<h3>What is telescope?</h3>
A telescope is an optical instrument that uses lenses, curved mirrors, or a combination of both to watch distant objects.
When atoms in a gas reach this temperature, they travel so quickly that when they collide, they release X-ray photons with wavelengths smaller than 10 nanometers.
Because the Earth's atmosphere prevents all X-rays from space, these wavelengths must be seen using space telescopes.
To study short-wavelength radiation, space telescopes must be put in orbit around the Earth.
Hence, space telescope is the correct answer.

here are no results for Did you guys know that saying ''Reeeee" is disrespectful and offensive? Ill explain: Because “Reeee” is used to mock people on the autism spectrum, supposedly mimicking a noise that someone on the spectrum might make
Explanation:
Answer:
Explanation:
Since 100C is the boiling temperature for water, for this problem we don't need to calculate the energy needed to get to the boiling point, just the heat or energy needed to vaporize the water to steam at 100C.
The formula for this is q=m(delta)
q is Joules of heat needed to vaporize the water to steam at 100C
m is mass in grams
Delta is in Joules per gram and can be looked up for water at this temperature. Here, it is approximately 2260J/g. This online lecture should help ease understanding: https://cabrillo.instructure.com/courses/10267/modules/items/256219
Therefore...
q=2.5g (2260J/g)= 5650J = 5.65kJ
