Answer:
Momentum is conserved in all three physical directions at the same time.
Explanation:
There is a peculiarity, however, in that momentum is a vector, involving both the direction and the magnitude of motion, so that the momenta of objects going in opposite directions can cancel to yield an overall sum of zero.
Answer:
Power, P is equal to 10 watts.
Explanation:
Given the following parameters;
Voltage drop, V = 50volts.
Resistance, R = 250ohms.
Power, P =?
The power developed in an electrical circuit is given by;
......equation 1
But we also know that;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, V = IR
Making I the subject of formula;
I = V/R
Substituting into equation 1;
P = (50²)/250
P = 2500/250
P = 10 watts.
Answer:
Explanation:
The condition for translation equilibrium is that is that the net force acting on the body must be zero.
The sum all the external forces acting on the body in horizontal as well as vertical direction must be zero.
∑Fₓ=0 and ∑Fy=0
now if the above two condition are satisfied the rigid body is said to be in translational equilibrium.
God bless... hope this help to clear your doubt.
Answer:
0
Explanation:
Since momentum is given by:
Therefore momentum is a vector quantity in the direction of velocity.
- Inelastic collision is the type of collision in which the masses combine after collision and start moving in the direction of the greater momentum but here in this case we have the momentum equal and opposite in direction.
<u>This case can be described mathematically as:</u>
since the mass and velocity are equal:
net momentum:
Answer:
The magnetic field unit in the International System is the tesla (T). A tesla is defined as the magnetic field that exerts a force of 1 N (newton) on a load of 1 C (coulomb) that moves at a speed of 1 m / s within the field and perpendicular to the field lines
Explanation:
Magnetic induction or magnetic flux density (B), is the magnetic flux that causes a diffusion charge in motion for each unit of normal area to the direction of the flow. It is also called the magnetic field strength.
The unit of magnetic flux density in the International System of Units is the tesla (T).
The tesla (symbol T), is the magnetic induction unit (or magnetic flux density) of the International System of Units (SI). It is defined as a uniform magnetic induction that, normally distributed over a surface of one square meter, produces through this surface a total magnetic flux of a weber.
<u>Equivalences:
</u>
1 T = 1 Wb · m-2 = 1 kg · s-2 · A-1 = 1 kg · C-1 · s-1
A Tesla is also defined as the induction of a magnetic field that exerts a force of 1 N (newton) on a load of 1 C (coulomb) that moves at a speed of 1 m / s within the field and perpendicular to the lines of magnetic induction.
1 T = 1 N · s · m-1 · C-1
Basic Unit in the Cegesimal System of Units (CGS): Gauss (G)
A gauss (G) is a magnetic field unit of the Cegesimal System of Units (CGS). A gauss (G) is defined as a maxwell per square centimeter.
1 gauss = 1 maxwell / cm2
A gauss is equivalent to 10-4 tesla:
1 T = 10,000 G
