Answer:
0.25 A
Resistance= 40 ohms
Explanation:
The first, and perhaps most important, the relationship between current, voltage, and resistance is called Ohm's Law, discovered by Georg Simon Ohm and published in his 1827 paper. Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual V=IR. Any Electrical device or component that obeys “Ohms Law” that is, the current flowing through it is proportional to the voltage across it ( I α V ), such as resistors or cables, are said to be “Ohmic” in nature.
Since we are not in a laboratory, we can not experimentally measure the current but it can be calculated from ohm's law.
Given that the four resistors are connected in series and
Req= R1 + R2 + R3 + R4
Since all are four ohm resistors
Req= 10 + 10+10+10 = 40ohms
Then;
V= 10 V
R= 40ohms
I= ???
From;
V=IR
I= 10/40
I= 0.25 A
Answer: hello the terms are missing but I have provided the answer ( the terms and matched them properly
answer :
- P WAVES
- S WAVES
- L WAVES
- R WAVES
Explanation:
This body wave is a compressional wave : P WAVES
This body wave is a shear wave : S WAVES
This surface wave moves from side to side : L WAVES
This surface wave moves up and down. : R WAVES
A body wave is a type of wave that passes through the interior of the earth and they are classified as ; P and S waves while surface waves are seismic waves that travel near the earth's surface
Answer:
The string will break with a speed of 20 m/s.
Explanation:
It is given that,
Tension at which the string just breaks, T = 400 N
Mass of the stone, m = 10 kg
Radius of the circle, r = 10 m
We need to find the speed at which the string will break. The boy continuously increases the speed of the stone. The tension acting on the stone is equal to the centripetal force. It is a force that acts towards the center of circle. It is given by :



v = 20 m/s
So, the string will break with a speed of 20 m/s. Hence, this is the required solution.
Answer:
9.6609 rad/s
10.143945 m/s
Explanation:
I = Moment of inertia = 3.75 kgm²
K = Kinetic energy = 175 J
r = Radius = 1.05 m
Kinetic energy is given by

The angular velocity of the leg is 9.6609 rad/s
Velocity is given by

The velocity of the tip of the punters shoe is 10.143945 m/s
Explanation:
This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.
