Answer:

[tex]\boxed {\boxed {\sf v \approx 1.46 \ m/s}}[/tex]

Explanation:

Momentum is the product of mass and velocity.

[tex]p=mv[/tex]

We know the mass is 65 kilograms and the momentum is 90 kilograms meters per second.

[tex]m= 65 \ kg \\p= 95 \ kg \ m/s[/tex]

Substitute the values into the formula.

[tex]95 \ kg \ m/s= 65 \ kg *v[/tex]

Since we are solving for velocity, we must isolate the variable (v). It is being multiplied by 65 kg. The inverse of multiplication is division, so we divide.

[tex]\frac {95 \ kg \ m/s}{65 \ kg }= \frac {65 \ kg *v}{65 \ kg}[/tex]

[tex]\frac {95 \ kg \ m/s}{65 \ kg }=v[/tex]

The kilograms cancel when divided.

[tex]1.46153846 \ m/s=v[/tex]

Let's round to the nearest hundredth. The 1 (in the thousandth place) tells us to leave the 6.

[tex]1.46 \ m/s \approx v[/tex]

The velocity is approximately 1.46 meters per second.

Violet

Explanation:

1. As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

2. Isaac Newton's experiment in 1665 showed that a prism bends visible light andthat each color refracts at a slightly different angle depending on the wavelength of the color.

Age of dino: Mesozoic era

End of earth a dessert: End of the Mesozoic

a layer: Paleozoic

1. All the relevant resistors are in series, so the total (or equivalent) resistance is the sum of the resistances of the resistors: 20 Ω + 80 Ω + 50 Ω = 150 Ω [choice A].

2. The ammeter will read the current flowing through this circuit. We can find the ammeter reading using Ohm's law in terms of the electromotive force provided by the battery: I = ℰ/R = (30 V)(150 Ω) = 0.20 A [choice C].

3. The voltmeter will measure the potential drop across the 50 Ω resistor, i.e., the voltage at that resistor. We know from question 2 that the current flowing through the resistor is 0.20 A. So, from Ohm's law, V = IR = (0.20 A)(50 Ω) = 10. V, which will be the voltmeter reading [choice F].

4. Trick question? If the circuit becomes open, then no current will flow. Moreover, even if the voltmeter were kept as element of the circuit, voltmeters generally have a very high resistance (an ideal voltmeter has infinite resistance), so the current moving through the circuit will be negligible if not nil. In any case, the ammeter reading would be 0 A [choice B].

Answer:

Part A

The ammeter reading for the current flowing through the second bulb, in the third circuit is 0.43 A

Part  B

The ammeter reading for the total current coming from the cell is 0.86 A

Explanation:

The given electric circuit schematics includes;

The number of bulbs in each circuit = 2 bulbs

The number of ammeter in each circuit = 1 ammeter

The number of cells in each circuit = 1

Each circuit have identical bulbs, cells and ammeters

Part A

Ammeter reading for the third circuit

The given reading for the total current going to the cell, [tex]I_T[/tex] = 0.86 A

The reading for the current flowing through one of the bulbs, I₁ = 0.43 A

Therefore, given that the bulbs are arranged in parallel, and the bulbs have identical resistance, 'R', the current flowing in the second bulb, I₂, is given by the current divider rule as follows;

[tex]I_2 = \dfrac{R}{R + R} \times I_T = \dfrac{R}{2 \cdot R} \times I_T = \dfrac{1}{2} \times I_T[/tex]

∴ The ammeter reading for the current flowing through the second bulb, in the third circuit I₂ = (1/2) × (0.86 A) = 0.43 A

Part B

Ammeter reading for the third circuit

The total current coming from the cell = The current passing through the bulbs = I₁ + I₂

The ammeter reading for the total current coming from the cell = 0.43 A + 0.43 A = 0.86 A = [tex]I_T[/tex]

Ans the answer is 0.25J

Explanation

i guess

Answer:

A

Explanation:

inertia Equation for All Object is k m R²

inertia Equation of Hollow Cylinder I = m R²

inertia Equation of Solid Cylinder I = ½ m R²

inertia Equation of Hollow Sphere I = ⅔ m R²

inertia Equation of Solid Sphere I = 2/5 m R²

to find the speed needed we can use Mechanical Energy (ME). or Total Energy.

ME = Translation Kinetic Energy + Rotation Kinetic Energi

ME = ½ m v² + ½ I w²

ME = ½ m v² (1 + k)

v² = 2ME / m(1+k)

sinnce all objects have the same mass, we can figure that v² is proportionally with 1/(1+k)

v²(hc) = 1/(1+1) = ½ = 0.5

v = 0.707

v²(sc) = 1/(1+½) = 2/3 = 0.67

v = 0.818

v²(hs) = 1/(1+⅔) = 3/5 = 0.6

v = 0.744

v²(ss) = 1/(1+²/5) = 5/7 = 0.71

v = 0.842

these is the ratio of speed they produce in the end of the arc with initial speed = 0 m/s

so, if we must give speed to the object so that it can reach the end of the arc, the fastest speed is given to hollow cylinder and the slowest speed is given to Solid Sphere

Then the answer is

HC, HS, SC, SS

Solid sphere, solid cylinder, hollow sphere, hollow cylinder  correctly lists the objects in order from fastest to slowest speed needed to make it through the arc.

A body's inertia is a characteristic that makes it resist attempts to move it or, if it is already moving, to change the speed or direction of it.

Mathematically:

inertia All Object is = k m R²

inertia of Hollow Cylinder I₁ = m R²

inertia of Solid Cylinder I₂ = ½ m R²

inertia of Hollow Sphere I₃ = ⅔ m R²

inertia of Solid Sphere I₄ = 2/5 m R²

Total kinetic energy of a body while it roll without slipping  = Translation Kinetic Energy + Rotation Kinetic Energi

= ½ m v² + ½ I w²

= ½ m v² (1 + k)

= 2 KE / m(1+k)

Since all objects have the same mass and, v² can be expressed as proportionally with 1/(1+k).

For hollow cylinder: v₁² = 1/(1+1) = ½ = 0.5

v₁ = 0.707

For solid cylinder: v₂²= 1/(1+½) = 2/3 = 0.67

v₂ = 0.818

For hollow sphere: v₃² = 1/(1+⅔) = 3/5 = 0.6

v₃ = 0.744

For solid sphere: v₄² = 1/(1+²/5) = 5/7 = 0.71

v ₄= 0.842

The objects in order from fastest to slowest speed needed to make it through the arc are correctly listed as:

solid sphere > solid cylinder > hollow sphere >  hollow cylinder.

Answer:

Energy = 0.25 kilowatt-hour

Explanation:

Given the following data;

Power = 25 Watts

Time = 10 hours

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

[tex] Power = \frac {Energy}{time} [/tex]

To find the energy consumed;

Energy = power * time

Substituting into the formula, we have;

Energy = 25 * 10

Energy = 250 Watt-hour

To convert to kilowatt-hour, we would divide by 1000;

Energy = 250/1000

Energy = 0.25 kilowatt-hour

Answer:

U² = 142.86 N

U¹ = 357.14 N

Explanation:

Taking summation of the moment about point A, we get the following equilibrium equation: (taking clockwise direction as positive)

[tex]W(2\ m) - U^2(7\ m) = 0[/tex]

where,

W = weight of boy = 500 N

U² = reaction ay B = ?

Therefore,

[tex](500\ N)(2\ m)-(U^2)(7\ m)=0\\U^2=\frac{1000\ Nm}{7\ m}\\[/tex]

U² = 142.86 N

Now, taking summation of forces on the plank. Taking upward direction as positive, for equilibrium position:

[tex]W-U^1-U^2=0\\500\ N - 142.86\ N = U^1\\[/tex]
