a car is running with the velocity of 72km/h. what will be its velocity after 5s if its acceleration is -2m/s2 ?
Answer:
36 km / hr
Explanation:
velocity final = velocity initial + accel * time
20 m/s + (-2)*5 ( 20 m/s = 72 km/hr)
10 m/s ( or 36 km/hr)
car starts from rest and reaches a velocity of 10 m/s in 10s a) Draw the v against t graph for the motion of the car? b) From the graph find: i) the slope of the graph. II) Area of the v against t graph bounded by the slope, on x-axis. c) What are the slope and area of v against t graph equal to respectively?

Habiba and selehadin have measured the voltage across a resistor to be 5.26V and the current flowing through in to be 0.41A they work out the resistance .
habiba says the resistance is 12.8 ohms .selehadin disagrees and says that is 13 ohm .
who is correct?.
Considering the definitipn of current, voltage, power, and Ohm's law,
CurrentThe flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.
VoltageThe conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.
Resistance
Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.
This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.
The resistance that is measured in ohms.
Ohm's law
Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.
Mathematically, Watt's law is expressed:
[tex]I=\frac{V}{R}[/tex]
So if you want to find resistance, the expression for its calculation is:
[tex]R=\frac{V}{I}[/tex]
This caseIn this case, you know:
V= 5.26 VI= 0.41 AReplacing:
[tex]R=\frac{5.26 V}{0.41 A}[/tex]
Solving:
R= 12.8 ohms
Habiba is right. The resistance is 12.8 ohms.

briefly explain distribution of charges on conductors
Answer:
The distribution of charge is the result of electron movement. Since conductors allow for electrons to be transported from particle to particle, a charged object will always distribute its charge until the overall repulsive forces between excess electrons is minimized.
Answer:
This is simply the movement and transportation of electrons
What acceleration would you expect a 100 kg individual to experience from a 1000N force?
Answer: 10 m/2^2
F=ma
Explanation:
Force = 1000N
1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)
a = 10 m/s^2

which type of energy is stored in chemical compounds and released in chemical reactions?
Answer:
potential
Explanation:
In the absence of friction, explain why the horizontal component of a projectile’s velocity is a constant.
Answer:
This downward force and acceleration results in a downward displacement from the position that the object would be if there were no gravity. The force of gravity does not affect the horizontal component of motion; a projectile maintains a constant horizontal velocity since there are no horizontal forces acting upon it
A) half as much
B) as much
C) two times as much
D) three times as much
Answer:
3 times as much
Explanation:
half as much would be 12%, as much would be 24%, and two times as much would be 48%.
3 times as much is 72, which is about 74%

what is the mass on mercury of an object that weighs 784 n on the earth’s surface?
Answer:
80 kg weighs 80 kg x 9.8 m/s2 = 784 kg m/s2, or 784 Newtons. The surface gravity of Mercury is 0.39 that of Earth's (table 10-1), so 80 kg weighs 784 N x 0.39 = 306 N.

what is a concentration?
Answer/Explanation:
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.
A concentration refers to a subject or study within a specific major. As part of the degree coursework, concentration classes count toward your major requirements as well.

Which statement is true about vectors?
Vectors need direction and magnitude to exist, otherwise, it becomes scalars that do not require direction to be expressed.
eg - Velocity is a vector as it needs direction, but speed is scalar and does not need direction
hope this helps
Answer:
a. All quantities in physics are not vectors. b. A vector may have either magnitude or direction. c. The vector's length should be proportional to its magnitude. d. Two vectors can be added only if they have the same direction.
If the activity of a source is 70 Bq after 2 years, and 35 Bq after 15 years. How long will be until the activity is 8.75 Bq?
Answer:
N = N0 e^-kt calling k the decay constant
70 = N0 e^-2 kt
35 = N0 e^-15 k
2 = e^(-2 + 15) k
.693 = 13 k
k = .0533
N0 = N e^kt
N0 = 70 e^(.0533 * 2) = 77.87
8.75 = 77.87 e^-(.0533 t)
ln .1124 = -.0533 t
t = -ln .1124 / .0533 = 41 yr
