Answer:
15.5 m/s.
Explanation:
Potential energy of the balloon has been converted to kinetic energy.
potential energy = kinetic energy.
mgh = ½mv².
10* 10* 12= ½ *10 *v²
1200 = 5v²
v²=1200÷5
v=√240
v= 15.49~15.5 m/s.
Electrons can't flow at different speeds at different points, they can't speed up suddenly after passing through a resistor.
V=IR
So V/R=I
Answer:
The internal resistance of the battery is 1.0 Ω.
Explanation:
Given that,
Voltage = 12,0 V
Resistance of each resistor = 6.0 Ω
Current = 4.0 A
When three resistors are connected in parallel.
We need to calculate the resistance
Using formula of parallel
Here, R₁ = R₂ = R₃
The equivalent resistance is
We need to calculate the internal resistance
Using ohm's law
Where, R = resistance
r = internal resistance
V = voltage
I = current
Put the value into the formula
Hence, The internal resistance of the battery is 1.0 Ω.
Explanation:
Water is compound made up of hydrogen and oxygen atoms.
Hydrogen and oxygen are elements that are joined together to form water.
A compound is a substance composed of two or more kinds of atoms/elements joined together in a definite grouping. The properties of a compound are different from those of the individual elements that are combined to make them up.
Water is made up of hydrogen and oxygen atoms in a ratio of 2 to 1;
An element is a distinct substance that cannot split up into simpler substances. Such substances are made up of one kind of atom. Hydrogen and oxygen are elements.
