Open circuit voltage is the voltage difference measured between two terminals when no current is being drawn or supplied. Short-circuit current is the current that flows when the voltage difference between terminals is forced to zero. No current flows in the circuit, but there is a voltage drop between the two points.

As a result, in an open circuit, the current through it is zero but the voltage is present. The current becomes zero and the power equals VI. When an open circuit is introduced, current flow through the circuit is interrupted. The voltage drop across each resistive element is zero when no current is flowing. However, the source potential difference appears to be open.

Through the act of counting and calculating the energy of single photons emitted from elements, gamma ray detectors calculate electromagnetic radiation.

Gamma-ray detection is carried out photon-by-photon, just as X-ray detection. By observing the impact they have on materials, gamma rays can be found. A gamma ray can drive an electron to a higher level or collide with it and cause it to scatter like a pool cue (Compton scatter) (photoelectric ionization).

Protons are transformed into neutrons, positrons, and electron neutrinos as part of the proton-proton chain, which generates a significant amount of energy. The primary reaction in the majority of main-sequence stars, including the Sun, is the proton-proton chain. A nuclear fusion reaction, the proton-proton chain releases energy as the energy in the nuclear bonds diminishes. To counteract the protons' natural tendency to resist one another, smaller nuclei must have more energy.

An atom of the unstable isotope germanium-71 can be created when a neutrino interacts with a gallium-71 atom. The germanium was then concentrated and removed chemically. As a result, neutrinos were discovered by monitoring germanium's radioactive decay.

The velocity with which the objects move together after the collision is 5.604 m/s

State the the law of momentum conservation.

The following is an explanation of the law of momentum conservation.

The bullet and the block have the same speed after colliding, therefore we utilize momentum conservation and account for that.

mv1_i + Mv2_i = mv1_f + Mv2_f

Given values from the question,

Mass of bullet = m =25 g = 0.025 kg

Mass of wooden block = M = 35 kg

Initial speed of bullet = v1_i = 250 m/s

Putting the values in the momentum conservation equation,

The rate at which the speed and direction of a moving object change over time is known as acceleration. Any movement, whether straighter, faster, or slower, is referred to as acceleration. The fact that the direction is constantly shifting causes motion on a circle to accelerate even though the speed is constant.

What is velocity?

The velocity of a body or object determines the direction of its motion. Speed is often measured as a scalar value. The most basic definition of a vector quantity is velocity. It gauges the rate at which a distance varies. It relates to the speed at which displacement is altering.

Initial height = 6ft

initial velocity v₀= 41i+3gj+27k

assume upwards, as +k acceleration

due to gravity= -9.8m/s²k or

=-32ft/s² k

initial height (s₀)= 6k

position of the ball, after t secs

s= s₀+v₀t+1/2a₀t²

s=6k+(41i+3gj+27k) t+1/2(-32k)t²

r(t)=s=41 i+3gtj +(27t-16t²=6)k ⇒ 1

If the ball is catch by a player 6A above ground

Answer:

Approximately [tex]0.64\; {\rm s}[/tex].

Velocity: approximately [tex]6.3\; {\rm m\cdot s^{-1}}[/tex].

(Assuming that air resistance is negligible, and that [tex]g = 9.81\; {\rm m\cdot s^{-2}}[/tex] assuming that the fall started from rest.)

Explanation:

If air resistance is negligible, acceleration will be constantly [tex]a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}[/tex] during the fall.  

Let [tex]x[/tex] denote the displacement. In this question, [tex]x = (-2.0)\; {\rm m}[/tex]. Note that [tex]x[/tex] is negative since the position after the fall is below the initial position.

The initial velocity at the beginning of the fall is [tex]u = 0\; {\rm m\cdot s^{-1}}[/tex] under the assumptions.

Let [tex]v[/tex] denote the final velocity right before landing. Apply the SUVAT equation [tex]v^{2} - u^{2} = 2\, a\, x[/tex] to find [tex]v\![/tex]. Rearrange this equation to obtain:

[tex]\begin{aligned}v &= \sqrt{2\, a\, x + u^{2}} \end{aligned}[/tex].

Substitute in [tex]a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}[/tex], [tex]x = (-2.0)\; {\rm m}[/tex], and [tex]u = 0\; {\rm m\cdot s^{-1}}[/tex] and solve for [tex]v[/tex]

[tex]\begin{aligned}v &= -\sqrt{2\, a\, x + u^{2}} \\ &= -\sqrt{2 \,((-9.81)\; {\rm m\cdot s^{-2}}) \, ((-2.0)\; {\rm m}) + (0\; {\rm m\cdot s^{-1}})^{2}} \\ &= \left(-\sqrt{2 \, (-9.81)\, (-2.0)}\right)\; {\rm m\cdot s^{-1}} \\ &\approx (-6.26)\; {\rm m\cdot s^{-1}} \\ &\approx (-6.3)\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

(Negative since the final velocity points downwards to the ground.)

In other words, the velocity right before landing would be approximately [tex](-6.3)\; {\rm m\cdot s^{-1}}[/tex].

The change in velocity during the fall would be:

[tex]\begin{aligned}v - u &\approx (-6.26)\; {\rm m\cdot s^{-1}} - (0\; {\rm m\cdot s^{-1}}) = (-6.26)\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

Divide the change in velocity by acceleration to find the duration [tex]t[/tex] of the fall:

[tex]\begin{aligned}t &= \frac{v - u}{a} \\ &\approx \frac{(-6.26)\; {\rm m\cdot s^{-1}}}{(-9.81)\; {\rm m\cdot s^{-2}}} \\ &\approx 0.64\; {\rm s}\end{aligned}[/tex].

The final velocity it attains is 70.7 m/s

Velocity is the directional velocity of an object in movement as a demonstration of its price of exchange in function as found from a specific body of reference and as measured by using a specific well-known time.

Speed is the time fee at which an item is shifting along a direction, at the same time as velocity is the rate and route of an object's movement. placed any other way, speed is a scalar cost, whilst pace is a vector.

Speed is the velocity at which something moves in a selected course. for example, the velocity of a car traveling north on a highway, or the velocity at which a rocket travels after launching.

Moment = force * perpendicular distance from the fulcrum

Taking the left end of the beam as the anticlockwise direction ad the right end of the beam as the clockwise direction:

Anticlockwise moment = F * (0.75 - 0.25)

In physics, an object's apparent weight, which reflects its actual weight, is a characteristic. When an object's force of gravity is not counterbalanced by a normal force that is equal to but opposed to it, the apparent weight of the object will differ from the actual weight of the object. An object's weight is equal to the strength of the gravitational force pulling on it by definition.

Given,

The radius of the wheel, r = 5.0 m

Time, t = 8.0 s

And the weight of the person, W = 670 N

The following formula is used to determine the person's apparent weight as she crosses the highest point of her motion:

R=m(g-a)

Let the mass of the person is,

a=((1rev/8s)×(2Πrad/1rev))×5m

a=3.08 m/s²
