Calculate the wavelength of light that has a frequency of 5.2 x 1012 1/s.
Answer:
Wavelength = 5.77 * 10^-5 meters.
Explanation:
Given the following data:
Frequency of light = 5.2 *10^12 Hz
We know that the Speed of light = 3.0 * 10^8 m/s
To find the wavelength of light;
Mathematically, wavelength is calculated using this formula;
[tex] Wavelength = \frac {speed}{frequency} [/tex]
Substituting into the equation, we have;
[tex] Wavelength = \frac {3*10^{8}}{5.2 *10^{12}} [/tex]
Wavelength = 5.77 * 10^-5 meters.

How efficient is a pulley system if it enables you to lift a 700.0 Newton engine (Fr) 0.550 meters (dr) if you exerted 35.7 Newtons (Fe) of force while pulling 11.43 meters (de) of rope?
Answer:
96.3%
Explanation:
Efficiency = Work input/Work output * 100%
Work done = Force * distance\
Work done by the engine is the work output = 700 * 0.55
Work output = 423.5Nm
Work done by you is the work input = 35.7*11.43
Work input = 408.051Nm
Efficiency = 408.051/423.5 * 100
Efficiency = 0.963 * 100
Efficiency = 96.3%
Hence the efficiency of the pulley system is 96.3%

A hydrogen atom has a radius of 2.5 x 10-11 m
Determine the radius of a magnesium atom.
Answer:
[tex]R = 1.5* 10^{-10}m[/tex]
Explanation:
Given
[tex]r = 2.5 * 10^{-11}m[/tex] -- radius of hydrogen atom
See attachment
Required
Determine the radius of magnesium atom (R)
From the attachment, the ratio of a hydrogen atom to a magnesium atom is:
[tex]Ratio = 6mm : 36mm[/tex]
Simplify
[tex]Ratio =1 : 6[/tex]
Represent the radius as ratio:
[tex]Ratio = r : R[/tex]
Substitute [tex]r = 2.5 * 10^{-11}m[/tex]
[tex]Ratio = 2.5 * 10^{-11}m : R[/tex]
Equate both ratios
[tex]2.5 * 10^{-11}m : R = 1 : 6[/tex]
Express as fraction
[tex]\frac{2.5 * 10^{-11}m}{R} = \frac{1}{6}[/tex]
Cross Multiply
[tex]R * 1 = 2.5 * 10^{-11}m * 6[/tex]
[tex]R * 1 = 2.5 * 6* 10^{-11}m[/tex]
[tex]R * 1 = 15* 10^{-11}m[/tex]
[tex]R = 15* 10^{-11}m[/tex]
[tex]R = 1.5*10* 10^{-11}m[/tex]
[tex]R = 1.5* 10^{1-11}m[/tex]
[tex]R = 1.5* 10^{-10}m[/tex]
Hence, the radius of the magnesium atom is: [tex]1.5* 10^{-10}m[/tex]

What is the impulse of a constant force of 50 newtons applied for 0.6 seconds
Answer:
30 kg·[tex]\frac{m}{s}[/tex]
Explanation:
Impulse is equal to the average force multiplied by the elapsed time, or
J=[tex]F_{av}[/tex]Δt
Your average force [tex]F_{av}[/tex] is 50 newtons because it was a constant force. Your elapsed time Δt was 0.6 seconds.
Multiply these values and you get an impulse of 30 kg·[tex]\frac{m}{s}[/tex]
A man drives south to work every
day. If his 55 mile commute
usually takes 0.75 hours, what is
his average velocity?
The man's average velocity is 73.3 mph (miles per hour).
What is average velocity?Average velocity is a measure of the rate of displacement of an object in a given direction. It is the total displacement of the object divided by the total time taken to cover that displacement. In other words, it is the distance an object travels divided by the time it takes to travel that distance. Average velocity is an important concept in physics, as it can provide insight into the motion of an object and the forces acting upon it. Average velocity can be calculated using the equation: velocity = displacement/time.
This can be calculated by dividing the distance (55 miles) by the time (0.75 hours). Mathematically, this can be expressed as:
velocity = (distance / time)
velocity = (55 miles / 0.75 hours)
velocity = 73.3 mph

Two resistors, A and B, are connected in series to a 6.0 V battery. A voltmeter connected across resistor A measures a potential difference of 4.0 V. When the two resistors are connected in parallel across the 6.0 V battery, the current in B is found to be 2.0 A. Find the resistances of A and B.
Answer:
Resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω
Explanation:
When the two resistors are in series, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B.
Given that V₁ + V₂ = 6.0 V and V₁ = 4.0 V,
V₂ = 6.0 V - V₁ = 6.0 V - 4.0 V = 2.0 V
Also, let the current in series be I.
So, V₁ = IR₁ and V₂ = IR₂
I = V₁/R₁ and I = V₂/R₂
equating both expressions, we have
V₁/R₁ = V₂/R₂
4.0 V/R₁ = 2.0 V/R₂
dividing through by 2.0 V, we have
2/R₁ = 1/R₂
taking the reciprocal, we have
R₂ = R₁/2
R₁ = 2R₂
From the parallel connection, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B. Since it is parallel, V₁ = V₂ = V = 6.0 V
Also, V₂ = I₂R₂ where I₂ = current in resistor B = 2.0 A and R₂ = resistance of resistor B
So, R₂ = V₂/I₂
= 6.0 V/2.0 A
= 3.0 Ω
R₁ = 2R₂
= 2(3.0 Ω)
= 6.0 Ω
So, resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω
The resistance of A is 6Ω while for B is 3Ω.
Definition of potential differencePotential difference is the amount of work done in moving a unit charge from one point to another.
When the two resistors are connected in parallel across the 6.0 V battery, the current in B is found to be 2.0 A, hence:
2 * Rb = 6 V
Rb = 3Ω
For the series connection:
I * 3 = (6 - 4)
I = 2/3 A
Hence:
(2/3) * Ra = 4
Ra = 6Ω
The resistance of A is 6Ω while for B is 3Ω.

A reference point allows you to determine the _____________of an object state state speed speed position position dimension
Answer:
Position.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
Hence, a reference point allows you to determine the position an object.

calculate the ground pressure of a 90kg gas cylinder the diameter of the cylinder is 1.1 m
Answer:
P = 928.09 Pa
Explanation:
Given that,
Mass of a gas cylinder, m = 90 kg
The diameter of the cylinder, d = 1.1 m
Radius, r = 0.55 m
We need to find the ground pressure. The pressure is equal to force per unit area. So,
[tex]P=\dfrac{F}{A}\\\\P=\dfrac{mg}{\pi r^2}\ (A\ is\ area\ of\ base)\\\\P=\dfrac{90\times 9.8}{\pi \times (0.55)^2}\\\\P=928.09\ Pa[/tex]
So, the ground pressure is 928.09 Pa.
