Answer:
The answer is 0.0013.
Explanation:
The answer is 0.0013 becuase the number is even and you have to divide it by ten if it is milligrams to kilograms so basically always divide by tens. Hope this is helpful <3
The experiment requires 0.0013 kg of sugar.
How conversion of milligram to kilogram is done?The milligram is the mass = 1/1,000 of gram (or) 0.0154 grains.
The milligram is an SI unit of weight where as kilogram is also a unit of weight in the metric system.In the metric system, " milli " is the prefix for 10⁻³ and " kilo " is the prefix of 10³.Abbreviation of mg - milligram, kg - kilogram.For example, 50 milligram is 50 mg and 50 kilogram is 50kg.kilograms = milligrams ÷ 1,000,000
The weight in kilograms is equal to the milligrams divided by 1,000,000.
Here,
1300 mg = ( 1300 ÷ 1,000,000) = 0.0013 kg
Hence, the answer is 0.0013 kg.

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 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

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.

As you add heat, what happens to the kinetic energy of atoms?
The atoms in a hot object move faster than atoms in a cold object.
Answer:
The atoms in a hot object move faster than atoms in a cold object. The atoms in a hot object have more kinetic energy than the atoms in a cold object. Adding heat to a substance will make the atoms vibrate more and when heat leaves the substance; the atoms will vibrate less. Potential energy is stored energy.

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 rock is thrown downwards from the edge of the Grand Canyon. With
what velocity will it hit the donkey-riding tourist who is 40 m below?
Answer:
Vf = 28 m/s
Explanation:
In order to find the final velocity of the rock, we will use the 3rd equation of motion. The third equation of motion for vertical direction is written as follows:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height dropped = 40 m
Vf = final velocity of the rock = ?
Vi = Initial Velocity of the rock = 0 m/s (since, rock was initially at rest)
Therefore,
(2)(9.8 m/s²)(40 m) = Vf² - (0 m/s)²
Vf = √(784 m²/s²)
Vf = 28 m/s

Explanation:
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
