If you were to travel from the equator to the higher latitudes (near either pole) on Saturn, the differential rotation would cause the length of a day that you would measure to be longer by ____ hour(s). [Number accurate to 2 places after the decimal.]
Answer:
Saturn's differential rotation will cause the length of a day measures to be longer by 0.4 hours
Explanation:
Differential rotation occurs due to the difference in angular velocities of an object as we move along the latitude of the or as we move into different depth of the object, indicating the observed object is in a fluid form
Saturn made almost completely of gas and has differential motion given as follows
Rotation at the equator = 10 hours 14 minutes
Rotation at high altitude = 10 hours 38 minutes
Therefore;
The differential rotation = 10 hours 38 minutes - 10 hours 14 minutes
The differential rotation = 24 minutes = 24 minutes × 1 hour/(60 minutes) = 0.4 hours
The differential rotation = 0.4 hours
Therefore, the measured day at the higher altitude will be 0.4 longer than at the equator.

Old thermometers contained very small amounts of mercury. The mercury in the photo has a melting point of −38.8 °C. What can you conclude about the melting point of the mercury in old thermometers?
A. Its melting point can only be determined when the mercury is burned.
B. Its melting point changes as the mercury’s temperature changes.
C. Its melting point equals −38.8 °C because it is mercury.
D. Its melting point is less than −38.8 °C because its volume is smaller.
Answer:
C. Its melting point equals −38.8 °C because it is mercury.
Explanation:
Given that the old thermometer contained a very small amount of mercury and the melting point of mercury is [tex]-30^{\circ}C[/tex].
The temperature at which any material starts changing from the solid-state to the liquid-state is known as the melting point of the material.
As the melting point of any material does not depends on the amount of material. So, whether there is a small amount of mercury or is a large amount of mercury.
Hence, the melting point remains [tex]-30^{\circ}C[/tex] because it is mercury.
So, option (C) is correct.
As per the definition above, there is no need to burn the mercury to determine the melting point, so option (A) is wrong.
The melting point does not depend on the initial temperature, mass, volume of the material, so options (B) and (D) are wrong.

Given a helicopter flying up and sideways at a velocity of 95 m/s at an angle of 35º to the ground, find the horizontal component of the velocity.
Answer:
The horizontal component of the velocity of the helicopter is approximately 77.82 m/s
Explanation:
The given parameters are;
The speed of the helicopter, v = 95 m/s
The angle in which the helicopter is flying = 35° to the ground
The horizontal component of the velocity is given by the component of the magnitude, R, of the velocity of the helicopter in the x-direction as follows;
[tex]v = \sqrt{v_x^2 + v_y^2}[/tex]
Where;
vₓ = v × cos(θ) = The horizontal component
[tex]v_y = v \times sin(\theta)[/tex] = The vertical component
∴ The horizontal component of the velocity, vₓ, of the helicopter with 95 m/s velocity moving at an angle of 35° to the horizontal is given as follos
vₓ = 95 × cos(35°) ≈ 77.82 m/s
The horizontal component of the velocity of the helicopter ≈ 77.82 m/s.

Where would the net force acting on a charge placed in a system of like charges be zero?
Answer:
If an object is electrically neutral it has no net charge becuase it has the same number of protons as it does electrons, which are opposite charges that offset each other. No, that just means that the sum of all its positive and negative amounts of charge equals zero.

Given :
An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west.
It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark.
To Find :
The total distance the ant traveled.
Solution :
Total distance travelled by ant = (distance between 14 and 20 inch mark) +
(distance between 20 and 16 inch mark)
Total distance = (20-14 ) + ( 20-16) = 6 + 4 = 10 inch.

To increase power, we need to
Explanation:
To increase power, it is necessary to decrease the work being done and decrease the time in which the work was completed. increase the work being done or decrease the time in which the work is completed.Ma
Answer:
If work is done faster, power is higher. If work is done slower, power is smaller. Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v. More power is seen when the system is both strong in force and fast in velocity.
Explanation:
A car started its motion from rest and accelerated for 6 seconds, with the acceleration of 4 m/s2. Then it decelerated for 5 seconds, with the acceleration of -1.6 m/s2. What was the velocity of the car after 6+5 seconds?
Answer:
16 m/s
Explanation:
from the formula: a = velocity/time
you calculate the velocity in both cases (when time is 5 sec and 6 sec) by using the formula: velocity = a x time
v (5 sec) =24 m/s
v (6 sec) = - 8 m/s
then : add v (5 sec) to v (6 sec) and the result is 16 m/s
How is acceleration related to force when mass is constant, according to Newton's second law of motion?
Answer:
According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.
[tex]f = ma[/tex]
[tex]a = \frac{f}{m} [/tex]
f = force
m = mass
a = acceleration
According to Newton's second law of motion, acceleration is directly proportional to the force.
What is Newton's second law of motion?According to Newton's second law of motion, an object's change in velocity is influenced by the force being applied to it. An object must accelerate in order to change its velocity. The rate at which an object's velocity alters over time is known as its acceleration.
Since both acceleration and force are vector quantities, the acceleration of an object is determined by the direction of the applied force. How much a net force will alter an object's velocity is described by Newton's second law of motion.

A helicopter pulls upward by means of a rope on a 250 kg crate to lift it UNIFORMLY. What is the net force on the crate?
Answer:
The net force = 0
Explanation:
The given information includes;
The mass of the crate = 250 kg
The way the helicopter lifts the crate = Uniformly (constant rate (speed), no acceleration)
In order to pull the crate upwards, the helicopter has to provide a force equivalent to the weight of the crate keeping the helicopter on the ground.
The weight of the crate = The mass of the crate × The acceleration due gravity acting on the crate
The weight of the crate, [tex]F_w[/tex]↓ = 250 kg × 9.81 m/s² = 2,452.5 N
The force the helicopter should provide to just lift the crate, [tex]F_{(helicopter)}[/tex]↑ = The weight of the crate = 2,452.5 N
The net force, [tex]F_{(net)}[/tex] = [tex]F_{(helicopter)}[/tex]↑ - [tex]F_w[/tex]↓ = 2,452.5 N - 2,452.5 N = 0
The net force = 0.
