If the rotation of a planet of radius 5.32 × 106 m and free-fall acceleration 7.45 m/s 2 increased to the point that the centripetal acceleration was equal to the gravitational acceleration at the equator, what would be the tangential speed of a person standing at the equator?
Answer:
v = 6295.55 m/s
Explanation:
Given that,
The radius of a planet, [tex]r=5.32\times 10^6\ m[/tex]
The free fall acceleration of the planet, a = 7.45 m/s²
We need to find the tangential speed of a person standing at the equator.
Also, the centripetal acceleration was equal to the gravitational acceleration at the equator.
We know that,
Centri[etal acceleration,
[tex]a=\dfrac{v^2}{r}\\\\v=\sqrt{ar}\\\\v=\sqrt{5.32\times10^6\times 7.45}\\\\v=6295.55\ m/s[/tex]
So, the tangential speed of the person is equal to 6295.55 m/s.
A coil is wrapped with 332 turns of wire on the perimeter of a circular frame (of radius 30 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is directed perpendicular to the plane of the coil. This field changes at a constant rate from 29 mT to 56 mT in 63 ms. What is the magnitude of the induced average E in the coil, over the time interval 63 ms during which the field changes
Answer:
[tex]E=84.5V[/tex]
Explanation:
From the question we are told that:
Number of Turns [tex]N=332turns[/tex]
Radius [tex]r= 30cm[/tex]
Field Change [tex]B=56mt-29mt=27mt[/tex]
Time [tex]t=63ms[/tex]
Generally the equation for Magnetic Field is mathematically given by
[tex]\frac{dB}{dt}=\frac{27*10^{-3}}{29*10^{-3}}[/tex]
[tex]\frac{dB}{dt}=0.9T/s[/tex]
Generally the Flux at 332 turns is mathematically given by
[tex]\phi=N*A*B[/tex]
Generally the equation for Area of coil is mathematically given by
[tex]A=\pi*r^2[/tex]
[tex]A=\pi*(r*10^{-2})^2[/tex]
Since
[tex]\phi=332*\pi*(\theta*10^{-2})^2*B[/tex]
Therefore
[tex]\frac{d \phi}{dt}=332*\pi*(900*10^{-4}*\frac{dB}{dt}[/tex]
Generally the equation for emf Magnitude is mathematically given by
[tex]E=\frac{d\phi}{dt}[/tex]
[tex]E=332*\pi*(900*10^{-4}*0.9[/tex]
[tex]E=84.5V[/tex]

In the Vector Addition Lab, the following data was collected for determining the displacement from the door of the Physics classroom to another location in the building: 2 m, West; 14.0 m, South; 25.0 m, East; 11.0 m, North; and 2 m, West. The magnitude of the resultant displacement from the physics classroom to the assigned location is closest to ___ meters. (Round to the nearest integer.)
Answer:
21 m
Explanation:
Since the displacement from the door is 2 m West, we have our vector as -2i. The vector representing 14.0 m South is -14.0j. The vector representing 25.0 m East is 25.0i. The vector representing 11.0 m North is 11.0j. And, the vector representing 2.0 m West is -2.0i.
So, to get our position vector at the other location, we add all the vectors together.
So, r = -2i + (-14.0j) + 25.0i + 11.0j - 2i
= -4i + 25.0i - 14.0j + 11.0j
= 21.0i -3j m
Now, if we assume the position vector for the door is at the origin, we have r₀ = 0i + 0j m
So, our displacement from the door is r - r₀ = 21.0i - 3.0j - (0i + 0j) = 21.0i - 3.0j
So, the magnitude of the resultant displacement |r - r₀| = √(21.0² + 3.0²)
= 3.0√(7.0² + 1)
= 3.0√(49 + 1)
= 3.0√50
= 3.0 × 7.0711
= 21.2
≅ 21 m to the nearest integer

A boiling liquid absorbs thermal energy (heat) at a rate of 450 W. The specific latent heat of vaporisation is 2.7 × (10 race to power 6)J / kg.how much liquid is vaporised in 9 minutes?
Answer:
0.09 kg
Explanation:
The details of boiling liquid are;
The rate of thermal energy absorption by the liquid, P = 450 W
The specific latent heat of vaporization, c = 2.7 × 10⁶ J/kg
The required information = The amount of liquid vaporized in t = 9 minutes
We have;
P = E/t
Where;
P = Power supplied by the heat source = The rate of absorption of thermal energy
E = The energy absorbed
t = The time
The energy absorbed in 9 minutes, E = P × t
∴ E = 450 W × 9 min × 60 s/min = 243,000 J
The heat required to evaporate 1 kg of liquid = The specific latent heat of vaporization, c = 2.7 × 10⁶ Joules
The mass of the liquid evaporated by the energy absorbed, E, m = E/c
∴ m = 243,000 J/(2.7 × 10⁶ J/kg) = 0.09 kg
Therefore, the mass of the liquid vaporized by the energy absorbed at a rate of 450 W, in 9 minutes, m = 0.09 kg.

Danny and Iskander sit on a see-saw. Iskander weighs 40 N and sits 1.2 meters from the pivot. Danny sits 0.8 m from the pivot and the see-saw is balanced. How much does Danny weigh?
Answer:
60N
Explanation:
According to the principle of lever: a torque can control if an object will spin or not.
The torque Iskander cause is 40*1.2=48 N-m
So for balanced, Danny should cause the same torque.
48/0.8=60, Danny weigh 60N.

Calcalculate potential energy given to a potato sack having a mass of 2 kg as I raise it to a height of 450 CM
Answer:
8.829 Joules
Explanation:
The potential energy of an object, is the energy it posses (the energy stored within the object) by virtue of its relative elevation or height, position, state, or arrangement
The potential energy of an object raised to a given height, P.E. = m·g·h
Where;
m = The mass of the object
g = The acceleration due to gravity, a constant ≈ 9.81 m/s²
h = The present height of the object
For the potato sack having a mass, m = 2 kg, and raised to a height, h = 450 cm = 0.45 m, we have;
The potential energy given to the potato sack, by raising its height, P.E. is given as follows;
P.E. = 2 kg × 9.81 m/s² × 0.45 m = 8.829 Joules
The potential energy given to the potato sack, P.E. = 8.829 Joules

Which of Newton's Laws is represented in this demo?
Answer:
Newton's first law
Explanation:
you see, when an object is in motion, it tends to stay in motion, but in your case, if a object is at rest, it usually stays at rest unless acted upon my an unbalanced force which is pulling card from under the coin extremely quick and because you pulled it extremely quick, the coin isn't light enough to be moved easily with the paper, nor enough friction and speed for the coin to continue sticking onto the piece of paper
A.K.A. the coin is heavy, which is why it did not move with the paper
Answer:
Newton's First Law - Law of Inertia
Explanation:
Newton's First Law, the Law of Inertia mentions that an object at rest will stay in rest until acted by another force. The penny's inertia will cause it to fall directly down into the cup because the magnitude of external force applied by the card will be too meager to have a notable effect.
An average 1.50 V Alkaline AA battery has 9,360 J of stored energy. If the battery is placed in a toy that requires 2.00 amperes of current to operate, how many minutes will the battery last before it runs out of energy?
Answer:
52 minutes
Explanation:
Given the following data;
Voltage = 1.5 V
Current = 2 Amperes
Energy = 9360 J
To find how many minutes will the battery last before it runs out of energy;
First of all, we would determine the power rating of the toy
Power = current * time
Power = 2 * 1.5
Power = 3 Watts
Next, we find the time;
Energy = power * time
9360 = 3 * time
Time = 9360/3
Time = 3120 seconds
To convert to minutes;
60 seconds = 1 minute
3120 seconds = 3120/60 = 52 minutes

A 5-kg box is pushed with a horizontal force of 100 N across a floor. What power output is neede d to push the box a distance of 60 meters in 2 minutes? (A) 10 W (B) 25 W (C) 30 W (D) 50 W
Answer:
(D) 50 W
Explanation:
Given the following data;
Mass = 5 kg
Force = 100 N
Distance = 60 N
Time = 2 minutes
Conversion:
1 minute = 60 seconds
2 minutes = 60 * 2 = 120 seconds
To find the power output required to push the box;
First of all, we would determine the work done in pushing the box.
Work done = force * distance
Workdone = 100 * 60
Workdone = 6000 Joules
Next, we find power output;
Power = workdone/time
Power = 6000/120
Power = 50 Watts

The drop in potential across a resistor in a circuit is 40 V. What is the current
flowing through the resistor if the resistance is 2.0 0? (use Ohmis law. V = IR
Answer:
Current, I = 20 Amperes.
Explanation:
Given the following data;
Voltage = 40 V
Resistance = 2 Ohms
To find current flowing through the resistor;
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, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Making current (I) the subject of formula, we have;
[tex] I = \frac {V}{R} [/tex]
Substituting into the formula, we have;
[tex] I = \frac {40}{2} [/tex]
Current, I = 20 Amperes.
