<u>Answer:</u> The unit of force, newton is equivalent to $kg.m/s^2$

<u>Explanation:</u>

Force is defined as the push or pull on an object with some mass that causes change in its velocity. It is also defined as the mass multiplied by the acceleration of the object. The S.I unit of force is Newton.

Mathematically,

$F=m\times a$

The S.I unit of mass is kilograms

The S.I unit of acceleration is $m/s^2$ (meters per second square)

So, the unit of force becomes: $kg.m/s^2$

Hence, the unit of force, newton is equivalent to $kg.m/s^2$

Answer:

The answer is "13% and 83%"

Explanation:

The highest power is generated for:

$\to \frac{dP}{dV_a}=0= I_s(e^{\frac{V_m}{V_t}} -1)-I_{Ph} +\frac{V_m}{V_t} I_s e^{\frac{V_m}{V_t}}$

Where voltage, $V_m$ , was its calculated maximum power wattage. This same following transcend national stable coins the power output:

$\to V_m=V_t \ In \frac{1+\frac{I_{ph}}{I_s}}{1+\frac{V_{m}}{V_t}}$

The accompanying consecutive values of $V_m$ are done utilizing iteration and an initial value of 0.5 V:

$\to V_m = 0.5,\ 0.542,\ 0.540 \ V$

Efficacy is equivalent to:

$\eta = |\frac{V_{m} I_{m}}{p_{in}}| =\frac{0.54 \times 0.024}{0.1}=1.3\%$

Currently, $I_m$ was calculated with the formula of voltage $V_m$ (4.6.1) as well as the sun is presumed to produce $100 \frac{mW}{cm^2}$ of power.

The fulfillment factor is equal to:

fill factor $= \frac{V_{m} I_{m}}{V_{oc}I_{sc}}= \frac{0.54 \times 0.024}{0.62 \times 0.025}=83\%$

where open circuit tension of equations (4.6.1) and I = 0. is calculated. The current is equal to the total current of the photo.

A spherical object (with non-uniform density) of mass 16 kg and radius 0.22 m rolls along a horizontal surface at a constant lin

Lapatulllka [165]

Answer:

Kr = 0.7618K

Explanation:

Suppose that the object's velocity is V, then his kinetic energy is:

K = $\frac{mv^{2} }{2}$

K = $\frac{(16)v^{2} }{2}$

K = 8 $v^{2}$

The rotational kinetic energy is

Kr = $\frac{Iw^{2} }{2}$

where I: The moment of inertia

ω: angular velocity

Kr = $\frac{(0.59)w^{2} }{2}$

Kr = 0.295 $w^{2}$

How the movement is without slipping, then

ω = $\frac{v}{r}$

ω = $\frac{v}{0.22}$

Thus

Kr = $\frac{0.295v^{2} }{0.22^{2} }$

Kr = 6.095 $v^{2}$

8 $v^{2}$ ----> 1

6.095 $v^{2}$ ----->?

Kr = 0.7618K

A karate master strikes a board with an initial velocity of 10.0 m/s, decreasing to 1.0 m/s as his hand passes through the board

kenny6666 [7]

The force exerted on the board by the karate master given the data is -4500 N

<h3>Data obtained from the question </h3>

Initial velocity (u) = 10 m/s
Final velocity (v) = 1 m/s
Time (t) = 0.002 s
Mass (m) = 1 Kg
Force (F) = ?

<h3>How to determine the force</h3>

The force exerted can be obtained as illustrated below:

F = m(v - u) / t

F = 1 (1 - 10) / 0.002

F = (1 × -9) / 0.002

F = -4500 N

A hockey puck with mass 0.3 kg is shot across an ice-covered pond. Before the hockey puck was hit, the puck was at rest. After t

JulsSmile [24]

Answer:

The net friction force is 8.01 N

Explanation:

Net friction force = mass of hockey puck × acceleration

From the equations of motion

v^2 = u^2 + 2as

v = 40 m/s

u = 0 m/s (puck was initially at rest)

s = 30 m

40^2 = 0^2 + 2×a×30

60a = 1600

a = 1600/60 = 26.7 m/s^2

The acceleration of the puck is 26.7 m/s^2

Net friction force = 0.3 × 26.7 = 8.01 N
