Answer:

7 m/s

Explanation:

Find the total mass

m1+m2 = total mass

700kg+300kg = 1000kg

Find the velocity of each mass

v1 = 10m/s

v2 = 0m/s

Find the combined momentum

m1v1 + m2v2 = mfvf

(700)(10)+(300)(0)=(1000)(vf)

7000=1000(vf)

7=vf

So the velocity of the two cars rolling together is 7 m/s

Answer:

1.F = 256 N

2.a = 8 m/s/s

By looking at the given information, you know force, and an acceleration. Therefore you have enough information to use the first formula.

F = ma

256 N = m * 8 m/s/s

m = 256 N/8 m/s/s

m = 32 Kg

Explanation:

Answer:

One joule also equals the energy required to move an electric charge of one coulomb through an electric potential difference of one volt (J = C · V). Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t).

Explanation:

Given that:

[tex]q_1 = + 4nC \\ \\ q_2 = -4nC \\ \\ q = 4nC[/tex]

[tex]P_1 = (0,0.04,0) m\\\\ P_2 = (0,0.05,0) m[/tex]

As [tex]q_1[/tex] [tex]\text{is nearer to }[/tex][tex]P_1 \& P_2[/tex] then [tex]q_2,q_1[/tex] [tex]\text{is positive, Thus}[/tex], [tex]E \limits^{\to}[/tex][tex]\text{ will be along the positive X-axis.}[/tex]

Recall that:

[tex]E ^{\to} = \dfrac{-dV}{dr}\implies E_y = \dfrac{-dV}{dy} \\ \\ = \int^{P_2}_{P_1}dV = -\int \limits ^{(0.05)}_{(0.04)}E_y \ dy \\ \\ \implies (V_{P_2}}-V_{(P_1)}) = \dfrac{-2q_5}{4 \pi \varepsilon _o} \int \limits ^{(0.05)}_{(0.04)} \dfrac{dy}{y^3} \\ \\ \implies (V_{P_2}}-V_{(P_1)}) = \dfrac{-2q_5}{4 \pi \varepsilon _o} \Big[ \dfrac{-1}{2y^2} \Big]^{0.05}_{0.04} \\ \\ \implies (V_{P_2}}-V_{(P_1)}) = \dfrac{q_5}{4 \pi \varepsilon _o} \Big[\dfrac{1}{y^2}\Big] ^{0.05}_{0.04}[/tex]

[tex]\\ \\ \implies (V_{P_2}}-V_{P_1}) = \dfrac{(4\times 10^{-9})(8\times 10^{-3})}{4 \pi (8.854 \times 10^{-12})} \Big [\dfrac{1}{(0.05)^2}-\dfrac{1}{(0.04)^2} \Big ]V \\ \\ (V_{P_2}}-V_{P_1}) = \mathbf{-64.71 \ volts}[/tex]

Answer:

  v = 4 m / s

Explanation:

In this exercise we are asked to find the speed of the wave, which is described by the expression

          v = λ f

in this case the wave has 4 nodes and 3 antinodes, in a length of 12 m

for a standing wave it is satisfied that we have a full wavelength and a half of another

          L = λ + ½ λ

          L = [tex]\frac{3}{2}[/tex] λ

          λ = ⅔ L

Cambien indicates that it has a frequency of

          f = 0.5 Hz

we substitute

          v = ⅔ L f

let's calculate

          v = [tex]\frac{2}{3}[/tex] 12 0.5

          v = 4 m / s

Answer:

The depth of the object below the surface of the liquid is 0.510 meters.

Explanation:

The hydrostatic pressure ([tex]P[/tex]), measured in pascals, experimented by the object is directly proportional to density of the fluid ([tex]\rho[/tex]), measured in kilograms per cubic meter, gravitational acceleration ([tex]g[/tex]), measured in meters per square second, and depth of the object ([tex]h[/tex]), measured in meters. That is:

[tex]P = \rho\cdot g \cdot h[/tex] (1)

If we know that [tex]P = 4500\,Pa[/tex], [tex]\rho = 900\,\frac{kg}{m^{3}}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the depth of the object is:

[tex]h = \frac{P}{\rho\cdot g}[/tex]

[tex]h = \frac{4500\,Pa}{\left(900\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]

[tex]h = 0.510\,m[/tex]

The depth of the object below the surface of the liquid is 0.510 meters.

The depth of the object below the liquid's surface will be

"0.510 m".

According to the question,

Object immersed, P = 4500 Pa

Density of liquid, ρ = 900 kg/m³

Acceleration due to gravity, g = 9.8 m/s²

We know the relation,

→ Hydrostatic pressure (P) = ρ.g.h

or,

Depth will be:

→ h = [tex]\frac{P}{\rho .g}[/tex]

By substituting the values,

     = [tex]\frac{4500}{900\times 9.8}[/tex]

     = [tex]\frac{4500}{8820}[/tex]

     = 0.510 m

Thus the above answer is appropriate.

Answer:

the initial kinetic energy of the basket ball is 4.8 J

Explanation:

The computation of the initial kinetic energy of the basket ball is shown below:

As we know that

Initial kinetic energy is

[tex]= \frac{1}{2}mv^2 \\\\= \frac{1}{2}\times 0.6 \times (4m/s)^2\\\\= \frac{1}{2}\times 0.6 \times 16m/s^2\\\\= 4.8 J[/tex]

Hence, the initial kinetic energy of the basket ball is 4.8 J

Answer:

T = 10 seconds

It means, it will make [tex]\dfrac{2}{20}=0.1\ \text{revolutions/second}[/tex] .

lt T be the period of the object. So,

[tex]T=\dfrac{1}{0.1}\\\\T=10\ s[/tex]

It will take 10 seconds for one revolution.

Answer:

* If it is an incandescent lamp, the increase in temperature of the towel could set it on fire,

* If the towel is wet, there could be a short circuit

Explanation:

Covering the lamp with a towel has several problems:

* If it is an incandescent lamp, the increase in temperature of the towel could set it on fire, which could be a danger

* If the lamp is not incandescent, the temperature rise of the towel is not very high,

* If the towel is wet, there could be a short circuit due to the humidity of the lamp with the wet towel

* If the towel is wet when touched, there could be a shock towards the person due to the electrical conduction

Consequently, covering the bulb with a towel is a serious mistake.

Answer:

A. That enough light of any frequency would cause electrons to flow.

Explanation:

A P E X

Scientists using classical, Newtonian physics expect to observe the photoelectric effect because enough light of any frequency would cause electrons to flow.

When a medium receives electromagnetic radiation, electrostatically charged particles are emitted from or inside it.

The emission of ions from a steel plate when light falls on it is a common definition of the effect. The substance could be a solid, liquid, or gas; and the released particles could be protons or electrons.

Scientists using classical, Newtonian physics expect to observe the photoelectric effect because enough light of any frequency would cause electrons to flow.

The flow of the electron is a must to understand the photo electric effect.

Hence option A is correct.

Answer:

10m/s

Explanation:

Vf=v0+at

30m/s=v0+2.5m/s^2*8s

Solve for v0=10m/s

Sorry for the vague explanation I'm on my phone right now. Hope this still helps!

Initial velocity of the car where final velocity of a car is 30m/s and it is accelerating at a rate of 2.5 [tex]m/s^{2}[/tex] over an 2.8 [tex]m/s^{2}[/tex] 8 second period of time is 10 m/s.

To find the initial velocity of the car, we can use the kinematic equation:

Final velocity (v) = Initial velocity (u) + (Acceleration (a) * Time (t)).

Given the final velocity (v) as 30 m/s, acceleration (a) as 2.5 [tex]m/s^{2}[/tex], and time (t) as 8 seconds, we can plug these values into the equation:

30 m/s = u + (2.5 [tex]m/s^{2}[/tex] * 8 s).

Now, solve for the initial velocity (u):

30 m/s = u + 20 m/s.

Subtract 20 m/s from both sides:

u = 30 m/s - 20 m/s = 10 m/s.

Therefore, the initial velocity of the car is 10 m/s.

Answer:

it helps you estimate how hard you're working (your activity intensity). perceived exertion is how hard you think your body is exercising. ratings on the scale are related to heart rate (how hard your heart is working to move blood through your body).

Explanation:

Answer:

The linear momentum of a particle with mass m moving with velocity v is defined as

p = mv (7.1)

Linear momentum is a vector . When giving the linear momentum of a particle you must

specify its magnitude and direction. We can see from the definition that its units must be

kg·m

s

. Oddly enough, this combination of SI units does not have a commonly–used named so

we leave it as kg·m

s

!

The momentum of a particle is related to the net force on that particle in a simple way;

since the mass of a particle remains constant, if we take the time derivative of a particle’s

momentum we find

dp

dt = m

dv

dt = ma = Fnet

so that

Fnet =
