What is the current of the ammeter?
Answer:
.6 A
Explanation:
V = IR
V/R = I
12/20 = I = .6 A
Answer:
a) 0.60 A
Explanation:
Given that,
→ Potential difference (V) = 12 V
→ Resistance (R) = 20 Ω
→ Current (I) = ?
Formula we use,
→ I = V/R
Let's solve the problem,
→ I = V/R
→ I = 12/20
→ [ I = 0.60 ]
Hence, option (a) is the answer.

Two coils connected in series have a resistance of 36 ohm and when connected in parallel have a resistance of 8ohm. Find resistance of each coil
Answer:
Explanation:
Remark
Two resistances in series has the form of
Rs= C1 + C2
Two resistances is parallel has the form of
Rp = (C1 *C2)/(C1 + C2)
The plan is to first of all find C1*C2 and use this information and C1 + C2 to find the individual resistances.
Givens
Rs = 36 ohms
Rp = 8 ohms
Solution
Rp = C1 * C2/(C1 + C2)
Rp = 8 ohms
C1 + C2 = 36 ohms
8 = C1*C2 / 36 Multiply by 36
8* 36 = C1*C2
C1*C2 = 288
Use Rs to solve for C1
C1 + C2 = 36C1 = 36 - C2(36 - C2) * C2 = 288
36*C2 - C2^2 =288 Multiply by - 1
-36C2 + C2^2 = -288 Add 288 to both sides
C2^2 - 36C2 + 288= 0 Factor this equation
(C2 - 12)(C2 - 24)
C2 - 12 = 0
C2 = 12
C2 - 24 = 0
C2 = 24
C2 = 24 or
C2 = 12
C1 = 36 - C2
C1 = 36 - 24 = 12
C1 = 36 - 12 = 24
Answer
C1 = 12 ohms or 24 ohms
C2 = 24 ohms or 12 ohms

A metal block has a mass of 5 grams and a volume of 1 cm3. What is the density of a piece of the same identical metal but with a different shape and different volume
Answer:
ρ = Mass / Volume definition of density
ρ = 5 g / 1cm^3 = 5 g / cm^3
Since the other object is made of the same metal its density is the same:
ρ = 5 g/cm^3
The density of a piece of the same identical metal but with a different shape and different volume is [tex]\rho = 5 g/cm^3[/tex].
What is density?The density of a substance is its mass per unit volume. Density gives information about how tightly the substance is packed together. The formula for density is
[tex]\rho ={\frac {m}{V}}[/tex]
Unit of density is grams per cubic centimetre.
What are uses of density?One of the most common uses of density is in how different materials interact when mixed together.Wood floats on water because it has a lower density than water, while an anchor sinks as the metal has high density.Balloons filled with helium gas float because the density of the helium is low than the density of air.Given:
Mass, [tex]m = 5 g[/tex]
Volume, [tex]V = 1 cm^{3}[/tex]
The density of metal is
[tex]\rho = \frac{5}{1}\\ \\\rho = 5 g/cm^{3}[/tex]
Since, the other object is made of the same metal. So, density is the same.

Answer:
Its B
Explanation:
Its B because i said its B alright cool bet
Second and third class levers are differentiated by the location of the load. The correct option is b.
The position of the weight in relation to the fulcrum distinguishes second-class levers from third-class levers.
The load is situated in a second-class lever halfway between the fulcrum and the applied force. The effort is placed between the fulcrum and the load in a third-class lever.
The mechanical advantage and the way these levers magnify force or motion depend on where the load is placed in relation to the fulcrum.
Thus, the correct option is b.

one particular descent goes from 2100m to 1600m. Assuming work done against friction is 90% of the potential energy change of the cyclist and the cycle, what increase in speed in Km/h can a rider attain by the end of the
descent?
Answer:
1/2 M V^2 = .1 M g H where 10% of PE goes into KE
V^2 = .2 g H = .2 * 9.8 * (2100 - 1600) = 980 m^2 / s^2
V = 31.1 m/s increase in speed during descent
1 km / hr = 1000 m / 3600 sec = .278 m/s
V = 31.1 m/s / (.278 m/s / km /hr)= 112 km/hr

A lamp is marked 24V, 100W. Describe an experiment to check that the electrical power supplied to the lamp is 100W when the p.d. across it is 24V.
In your account you should
* include a circuit diagram,
* state the readings that are taken,
* show how the result is calculated from the readings.
The electrical power supplied to the lamp is 100W when the p.d. across it is 24V and the current is 4.2 A.
What is electrical power?Electrical power is the rate at which electrical work is done.
The unit of electrical power is Watts.
Power = Current × VoltageThe experiment will require a 24V Battery, a Lamp marked 24V, 100 W, a key, wires, a rheostat, a voltmeter and an ammeter.
The circuit is completed and the rheostat is adjusted to provide until the voltmeter reads 24V.
The ammeter reading is taken as well.
When the voltmeter reading is 24V, it can be seen that' the ammeter reading for current is approximately 4.2 A.
Calculating, the power of the lamp:
Power = 24 × 4.2 = 100 W
Therefore, the electrical power supplied to the lamp is 100W when the p.d. across it is 24V and the current is 4.2 A.
