Answer:
Answer: 1/17/2020
Potential energy is directly related to the height of an object. Point 1 is higher than point 4, so the potential energy is greater at point 1.

Why do high water temperatures reduce the amount of fish in a water ecosystem? A. High temperatures decrease the nutriet level B. High temperatures can lower pH of the water C. High temperatures can decrease turbidity D. High temperatures can reduce the amount of dissolved oxygen in the water
Answer:
The correct option is D
Explanation:
Generally when there is an increase in temperature of water the solubility of oxygen decrease and this would in turn decrease the amount of fish in water due to the fact that fish require oxygen soluble oxygen to survive
A displacement vector begins at the point (2,3) on a Cartesian plane and ends at (5, 7). Calculate the length of this vector
Answer:
The length is d = 5
Explanation:
We must identify the respective coordinates of both points.
(x1,y1) = (2,3)
(x2,y2) = (5,7)
Now we know the distance equation of a straight line:
[tex]d=\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} } \\d=\sqrt{(5-2)^{2} +(7-3)^{2} }\\ d=\sqrt{9+16} \\d=5[/tex]

A 100.0-kg bakery sign hangs from two thin cables as shown.
What is the tension in each cable?
Answer:
1. T₁ = 500 N
2. T₂ = 866 N
Explanation:
Please see attached photo for the diagram.
Thus, we can obtain obtained the value of T₁ and T₂ as follow:
1. Determination of T₁
Angle θ = 30
Hypothenus = 100 kg
Opposite = T₁ =?
Sine θ = Opposite /Hypothenus
Sine 30 = T₁ / 100
Cross multiply
T₁ = 100 × Sine 30
T₁ = 100 × 0.5
T₁ = 50 Kg
Multiply by 10 to express in Newton
T₁ = 50 × 10
T₁ = 500 N
2. Determination of T₂
Angle θ = 60
Hypothenus = 100 kg
Opposite = T₂ = ?
Sine θ = Opposite /Hypothenus
Sine 60 = T₂ / 100
Cross multiply
T₂ = 100 × Sine 60
T₂ = 100 × 0.8660
T₂ = 86.6 Kg
Multiply by 10 to express in Newton
T₂ = 86.6 × 10
T₂ = 866 N
Bob wanted to investigate the effects of plant fertilizer. He bought three identical plants and gave plant 1 fertilizer every morning; plant 2 fertilizer once a week, and he didn't use any fertilizer on plant 3. Bob watered each plant every morning and set all three plants on the windowsill so they would all have the same amount of sunlight. He measured the height of each plant once a week . He plotted plant height (y-axis)vs time (x-axis) for each plant. What is the independent variable * 1 point
Answer:
TIME he applied the fertilizer to each plant
Explanation:
Independent variable in an experiment is the variable that is subject to change or manipulation by the experimenter. In this experiment, Bob wanted to investigate the effects of plant fertilizer. Bob sets up the experiment by applying the fertilizer to each plant at DIFFERENT TIMES i.e. plant 1-every morning, plant 2-once a week, plant 3-never.
Based on this, it is obvious that the independent or manipulated variable is the TIME at which he applied the fertilizer. On the other hand, the dependent or measured variable is the height of the plants.

A truck has mass of 1000 kg. What force will give it an acceleration of 1.5 m/s2
Given:
Answer
Unknown:
Formula
Substitute the numerical
values in the formula
Final Answer
Answer:
F = 1500 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of all forces must be equal to the product of mass by acceleration.
ΣF = m*a
F = 1000*1.5
F = 1500 [N]
A car weighs 2,000 kg. It moves along a road by applying a force on the road with a parallel component of 560 N. There are two passengers in the car, each weighing 55 kg. If the magnitude of the force of friction experienced by the car is 45 N, what is the acceleration of the car?
Answer:
The acceleration of the car is 0.244 m/s²
Explanation:
Given;
mass of the car, m = 2,000 kg
applied parallel force on the car, F = 560 N
mass of the two passengers, m = 2 x 55 kg = 110 kg
frictional force on the car (reducing horizontal motion), Fk = 45 N
Weight of the car acting downward, W = 2,000 x 9.8 = 19,600 N
weight of the two passengers acting downward, w = 110 x 9.8 = 1078 N
The net horizontal force on the car is given by;
∑Fx = F - Fk
∑Fx = 560 - 45
∑Fx = 515 N
Apply Newton's second law of motion;
F = ma
where;
m is the total mass of the system = mass of car + mass of passengers
m = 2000 + 110 = 2,110 kg
a = ∑Fx / m
a = 515 / 2110
a = 0.244 m/s²
Therefore, the acceleration of the car is 0.244 m/s²
1. List the point where the car has the greatest potential energy.
2. List the point where the car has the least potential energy.
3. List the point where the car has the greatest kinetic energy.
4. List the point where the car has the least kinetic energy.
Answer:
1) The point where the car has the greatest potential energy is Point A
2) The point where the car has the least potential energy is Point C
3) The point where the car has the greatest kinetic energy is Point C
4) The point where the car has the greatest kinetic energy is Point A
Explanation:
The potential energy of the car is given by the formula, PE = Mass × Gravity × Height
Therefore, as the height increases, the potential energy of the car increases
The total mechanical energy of the car, which is constant, is given by the following equation
The total mechanical energy = The Potential Energy + The Kinetic Energy
Therefore, at the point where the potential energy is lowest, the kinetic energy is highest.

a wire has current 5A in it.how much charge pass a point in wire in 2 min..???
Answer:
600 Coulomb
Explanation:
Electric Current refers to the charge passing through unit cross section of a wire per second.
Current ( C / sec) = 5A = 5C / sec
So, 5C charge passes through the wire in one second, then, amount of charge passing through a cross section of the wire in 120 seconds is :
5C * 120 = 600 Coulumb
