Answer:
By insulating our homes, we reduce the demand for energy and burn less fuel, which helps combat climate change and protects the planet. Insulating the loft, walls and floor of your home is a great way to reduce energy bills every year from a one-off activity!
Explanation:
I really hope this helps! Stay safe! ✌
Answer:
2. +0.2 C
Explanation:
When the two spheres touch, the total charge will be redistributed such that the two spheres are at same potential:
The potential can be rewritten as ratio between the charge on the sphere (Q) and the capacitance of the sphere (C):
Since the two spheres are identical, they have same capacitance:
So we can write
And since the total charge is
And this charge will be redistributed equally on the two spheres (
), we have
Answer:
Explanation:
<u>The question is asked in portuguese</u>
<u>Hence, it will be answered in portuguese</u>
1kg = 1000g
e
1 g = 1000mg
então
1 kg = 1 x (1000 x 1000)
1 kg = 1x 1.000.000
1 kg = 1.000.000mg
assim
1 comprimido -------------> 0,025 mg
x comprimido ------------> 1.000.000 mg ( só cruzar)
0,025(x) = 1(1.000.000)
0,025x = 1.000.000
x = 1.000.000/0,025
x = 40.000.000
<h3>1kg são feitos 40.000.000( Quarenta milhões de comprimidos)</h3>
Gamma rays are found in extremely hot regions and they have the smallest wavelength but the most energy. They can be found by the effects they have on matter and it do few basic things with matter, it can collide with a electron and bounce of it as a billiard ball.
Answer;
<u>= 56.96 mA</u>
Explanation;
From the Ohm's law;
V = IR, where V is the potential difference in volts, I is the electric current in amperes and R is the resistance in ohms.
V = 4.5 volts, R = 79 Ω
Making I the subject of the formula we get;
I =V/R
= 4.5 /79
= 0.05696 A
But, 1 A = 1000 mA
Thus; 0.05696 × 1000
<u>= 56.96 mA</u>
