Answer:
11.6 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{580}{50} = 11.6 \\ [/tex]
We have the final answer as
11.6 m/s²Hope this helps you
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)

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

What does a higher value of k and a lower value of k tell about the strength of the spring? (Hint: In which case is it soft or stiff?)
Answer:
' In layman's terms, the k variable in Hooke's law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object's material alongside its shape and Proportons

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.

what supports a white dwarf against the crush of gravity?
Answer: In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.
Explanation:
Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.
What is Degeneracy pressure?Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.
The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

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 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
