Answer: Hydrogen and Helium > Hydrogen compounds > Rocks > Metals
Explanation: The solar nebular system contains 98% Light Gases of both Hydrogen and Helium (produced in the Big Bang); followed by 1.4% of Hydrogen Compounds including water, methane, and ammonia; then followed by 0.4% of Rocks like Silicates; and lastly 0.2% of Metals including Iron, Nickel and Aluminium.
Answer: Hi!
A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.
Hope this helps!
Answer:
Explanation:
GIVEN
Force (F) = 8 N
Distance (d) = 2.5 metres
Work done = ?
WE know we have the formula
work done = F * d
Work done = 8 * 2.5
= 20 Joule
Hope it helps :)
Answer:
<h3>
a)</h3>
<u>=> R= 6 Ohms(Ω)</u>
<h3>b)</h3>
<em>these lights operate at the usual 240 volts direct from the main electricity supply. Therefore,</em>
<em>R and 100 can interchange places</em>
<u>=> R = 576 Ω</u>
<u></u>
By Ohm's Law:
=> 240 = I × 576
=>
=> I = 0.417 A
<h3 /><h3>c)</h3>
I don't know it's resistance,... so sorry
<h3>d)</h3>
The brightness of the bulb in series is <em><u>less than</u></em> when they're placed individually.
For bulbs in series their resistance gets added to form the equivalent resistance of the two bulbs.
Their resistances are nothing but mere numbers and the sum of two numbers(positive of course) is greater than the numbers.
So, the effective resistance of some bulbs in series <u>is more</u> than the individual resistance.
And
<em>Brightness, i. e., Power</em>
If resistance increases, Power decreases.
Here, the effective resistance was for sure larger, therefore resistance was increasing, hence power decreased taking brightness along with it.
The displacement of Edward in the westerly direction is determined as 338.32 km.
<h3>What is displacement of Edward?</h3>
The displacement of Edward can be determined from different methods of vector addition. The method applied here is triangular method.
The angle between the 200 km north west and 150 km west = 60 + 90 = 150⁰
The displacement is the side of the triangle facing 150⁰ = R
R² = a² + b² - 2abcosR
R² = 150² + 200² - (2x 150 x 200)xcos(150)
R² = 62,500 - (-51,961.52)
R² = 114,461.52
R = 338.32 km
