A fleeing student covered a distance of 210 meters in 35 seconds. what is the student's speed in meters/second? what is the student's speed in meters/minute?
Explanation:
Given that,
A student covered a distance of 210 meters in 35 seconds.
We need to find the student's speed in meters/second and also in meters/minute.
Speed, v = distance (d)/time (t)
So,
[tex]v=\dfrac{210\ m}{35\ s}\\\\=6\ m/s[/tex]
We know that, 1 minute = 60 seconds
[tex]6\dfrac{m}{s}=6\times \dfrac{m}{(\dfrac{1}{60})\ \text{minutes}}\\\\=360\ \text{meters/minutes}[/tex]
Hence, the student's speed is 6 m/s or 360 meters/minute.
A farmer is attempting to take a chicken across a river in a motorboat while a fox waits on shore with a bag of grain. If the river has a current with a velocity of 2.0 m/s and the boat maintains a speed relative to the water of 4.5 m/s, in which direction (angle) should the farmer point the boat so that the boat follows a straight path directly across the river?
Answer:
The farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river
Explanation:
The given parameters are;
The river current velocity = 2.0 m/s
The boat speed relative to the water = 4.5 m/s
Therefore, for the boat to have a resultant velocity that will follow a straight path directly across the river, we have;
The water current velocity, 2 m/s, the relative speed of the boat, 4.5 m/s, and the resultant velocity, v, form a right triangle, with the water current being the base, and the boat's relative speed being the hypotenuse side, while the height is the resultant velocity
Therefore, we have;
The direction of the boat relative to the direction of current the river = θ
The relative speed of the boat × sin(θ°) = The river current velocity
∴ sin(θ°) = The river current velocity/(The relative speed of the boat)
Which gives;
sin(θ°) = 2 m/s/(4.5 m/s) = 2/4.5 = 4/9
θ = sin⁻¹ = sin⁻¹(4/9) ≈ 26.39°
Therefore, the farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river.

Eric has a mass of 19.0 kg on the earth. What is Eric's weight on earth? What is Eric's weight on Mars? where the acceleration of gravity is approximately 0.381 of that of Earth's? ________.
Answer:
Weight on Earth = We = 186.2 N
Weight on Mars = Wm = 70.94 N
Explanation:
The weight of an object is defined as the force applied on the object by the gravitational field. The magnitude of weight is given by the following formula:
W = mg
were,
W= Weight of Eric
m = mass of Eric
g = acceleration due to gravity
ON EARTH:
W = We = Eric's Weight on Earth = ?
m = Eric's Mass on Earth = 19 kg
ge = acceleration due to gravity on Earth = 9.8 m/s²
Therefore,
We = (19 kg)(9.8 m/s²)
We = 186.2 N
ON MARS:
W = Wm = Eric's Weight on Mars = ?
m = Eric's Mass on Mars = 19 kg
gm = acceleration due to gravity on Mars = 0.381(ge) = (0.381)9.8 m/s² = 3.733 m/s²
Therefore,
Wm = (19 kg)(3.733 m/s²)
Wm = 70.94 N

A 0.5 kg yellow bouncy ball rolls to the right at a speed of 8 m/s while a 0.25 kg blue bouncy ball rolls
to the left towards it with a speed of 4 m/s. After the collision, the blue bouncy ball rolls to the right
with a speed of 12 m/s. How fast is the yellow ball rolling and in what direction?
Explanation:
Let yellow ball be m1 = 0.5kg with u1 = 8 m/s and blue ball be m2 = 0.25 kg with u2 = - 4 m /s respectively.
After collision, blue ball travels 12 m/s.
Using conservation of Linear Momentum :
m1u1 + m2u2 = m1v1 + m2v2
0.5* 8 + 0.25 * - 4 = 0.5 * v1 + 0.25 * 12
v1 = 0 m/sec i.e. Yellow ball comes to rest.

why is the unit of temperature is called derived unit
Explanation:
The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.
Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units

Describe voltage in terms of charge and electrons.
PLEASE HELP I WILL GIVE BRAINLIEST
Answer:
Voltage is a measure of how much energy is delivered to charge. At its most basic, an electron (basic charge) is imparted 1.602×10^−19 joules when moved through an electric potential difference of one volt. An electron is then said to have an energy of 1 electronvolt. So, voltage is energy divided by charge.

Which explains how to calculate the average acceleration of a moving object?
1.Divide the change in velocity by the change in time.
2.Multiply the change in time by the change in velocity.
3.Divide the change in time by the change in velocity.
4.Subtract the velocity from the change in time.
Answer Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed.

A motorboat heads due west at 15 m/s across a river that flows due south at 7.5 m/s. What is the magnitude and direction of the resultant velocity in m/s? Round off answer to 2 decimal places.
Answer:
16.77 m/s, 26.57° south of west
Explanation:
The two velocities form a right triangle. Use Pythagorean theorem to find the magnitude of the resultant velocity.
v² = (-15 m/s)² + (-7.5 m/s)²
v = 16.77 m/s
Use trig to find the angle.
tan θ = ((-7.5 m/s) / (-15 m/s))
θ = 26.57° south of west

Which of the following is most likely to happen when energy is transferred to an object A) the object will stay exactly the same B)The object Will begin to move C)the force on the object will decrease D) the mass of the object will increase
Answer:
B. the object will begin to move
Explanation:
If energy is transferred the object will definitely change so it CANNOT be "A". If you add energy the object will have more force so it CANNOT be "C". The mass of an object can't increase just by giving an object energy so it CANNOT be "D"
When energy is transferred to an object, the object is most likely to move either it gains a kinetic energy or it undergo a thermal vibration if thermal energy is applied.
What is energy transfer?Energy can be transferred from its high energetic area to less . All forms of energy can be transferred like this.For example, heat energy can be transferred through various modes such as conduction, convection, radiation etc.
When an object gain some energy its particles starts to vibrate and move apart. This makes the intermolecular force of attraction between molecules weaker than before and they tend to be more reactive.
The energy transferred to an object does not make any change in mass, or any of its innate properties or does not apply any force. Therefore, option B is correct.

Maria walks 20 ft north, 35 ft east, and 20 ft south to get to the pool. Find her distance and displacement.
Answer: distance = 75ft
displacement = 35ft east
The required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.
What are distance and displacement?To solve this problem, we first need to understand the difference between distance and displacement.
Distance is the total length traveled by an object, regardless of its starting and ending points. In this case, the distance traveled by Maria would be the sum of the distances of each segment of her journey,
Distance = 20 ft + 35 ft + 20 ft = 75 ft
Displacement, on the other hand, is the straight-line distance from the starting point to the ending point, measured in a straight line.
So let's assume the movement of maria on coordinate where North and East are positive movements and West and south are negative now add the distances,
Displacement =20 + 35 - 20 = 35 ft
Thus, the required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.
