The center of mass of a cow and the center of mass of a tractor are 208 meters apart. The magnitude of the gravitational force of attraction between these two objects is calculated to be 1.8 × 10-9 newtons.
What would the magnitude of the gravitational force of attraction be between these two objects if they were 416 meters apart?
A.
1.62 × 10-9 newtons
B.
3.6 × 10-10 newtons
C.
9 × 10-10 newtons
D.
4.5 × 10-10 newtons
Answer:
Choice: D.
Explanation:
Newton’s Law of Universal Gravitation
It states that objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance between them. The formula is:
[tex]\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]
Where:
m1 = mass of object 1
m2 = mass of object 2
r = distance between the objects' center of masses
G = gravitational constant: [tex]6.67\cdot 10^{-11}~Nw*m^2/Kg^2[/tex]
The center of mass of a cow is at a distance of r=208 m from the center of the mass of a tractor. The gravitational force of attraction is [tex]F=1.8\cdot 10^{-9}\ N[/tex]. It's required to find the new force of attraction F' if the distance was r'=416 m.
It can be noted that r'=2r. If the distance is doubled, the new force is:
[tex]\displaystyle F'=G{\frac {m_{1}m_{2}}{(2r)^{2}}}[/tex]
[tex]\displaystyle F'=\frac{1}{4}G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]
Substituting the original value of F:
[tex]\displaystyle F'=\frac{1}{4}\cdot 1.8\cdot 10^{-9}\ N[/tex]
Operating:
[tex]\displaystyle F'=4.5\cdot 10^{-10}\ N[/tex]
Choice: D.

A box that weight 1000 N is lifted a distance of 20.0 m straight up by a rope and pulley system . The work is done in 10.0 seconds what is the power devloped
Answer:
P = 2,000 W
Explanation:
Work and Power
Work is the amount of energy transferred by a force over a distance. It's a scalar quantity, with SI units of joules.
If both the force F and displacement s are parallel, then we can use the equivalent scalar formula:
W=F.s
Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.
The power can be calculated as:
[tex]\displaystyle P=\frac {W}{t}[/tex]
Where W is the work and t is the time.
A box with a weight of 1,000N is lifted by s=20 m by a rope and pulley system. The system exerts a force equal to the weight of the box, thus F=1,000 N. The work done by the system is:
W =1,000 N * 20 m
W = 20,000 J
Now we calculate the power developed by the system in t=10 seconds:
[tex]\displaystyle P=\frac {20,000}{10}[/tex]
P = 2,000 W

What is the magnitude of the centripetal
force that must be applied in order for a
0.5 kg ball on a 2.0 m string to spin with
uniform circular motion at 5.0 m/s?
Answer:
Explanation:
6.25
The magnitude of the centripetal force that must be applied is 6.25 N.
The given parameters;
mass of the object, m = 0.5 kgvelocity of the object, v = 5 m/sradius of the string, r = 2 mThe magnitude of the centripetal force that must be applied is determined by the product of the mass of the object and the centripetal acceleration.
The centripetal force is calculated as follows;
[tex]F_c = ma_c = \frac{mv^2}{r} \\\\F_c = \frac{0.5 \times 5^2}{2} \\\\F_c = 6.25 \ N[/tex]
Thus, the magnitude of the centripetal force that must be applied is 6.25 N.

A) 10
B) 20
C) 30
D) None of these
Explain how you got your answer
Answer:
30 maybe?
Explanation:
Answer:- 30 km/hr
Given :- Distance covered by Salesman 50 km
Time taken;- 2 hrs and 30 minutes
Speed of salesman: Distance/ time taken
50 / 2 1/2 = 20 km/hr
He has make it 5/6 less
2 1/2 —5 / 6 = 5 / 3 hrs
Speed : Distance / Time
50 km / 5/3 = 30
He has to travel at 30 km per hour.

7) Which statement below best describes the motion of the cart under the conditions shown in the image below?
Newton’s second law: The acceleration (a) of an object is directly proportional to the force on the object (F) and inversely proportional to its mass (m).
F < The greater the force, the greater the acceleration
a = -- OR F=ma
M< The greater the mass the less the acceleration
Answer:
there is the answer
Explanation:
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

A ball with a mass of 0.7 kg is thrown straight upward, flies up to its maximum height, and
then falls back down. If the ball was initially thrown with a kinetic energy of 250.1 joules,
how much potential energy will the ball have at its maximum height? Round your answer to
the tenths place.
Answer:
250.05 J
Explanation:
From the question given above and, the following data were obtained:
Mass (m) = 0.7 kg
Kinetic energy (KE) = 250.1 J
Potential energy (PE) =?
Next, we shall determine the velocity of the ball. This can be obtained as follow:
Mass (m) = 0.7 kg
Kinetic energy (KE) = 250.1 J
Velocity (v) =?
KE = ½mv²
250.1 = ½ × 0.7 × v²
250.1 = 0.35 × v²
Divide both side by 0.35
v² = 250.1 / 0.35
Take the square root of both side
v = √(250.1 / 0.35)
v = 26.73 m/s
Next, we shall determine the maximum height reached by the ball. This can be obtained as follow:
Initial velocity (u) = 26.73 m/s
Final velocity (v) = 0 m/s (at maximum height)
Acceleration due to gravity (g) = 9.8 m/s²
Maximum height (h) =.?
v² = u² – 2gh (since the ball is going against gravity)
0² = 26.73² – (2 × 9.8 × h)
0 = 714.4929 – 19.6h
Collect like terms:
0 – 714.4929 = – 19.6h
– 714.4929 = – 19.6h
Divide both side by –19.6
h = –714.4929 / –19.6
h = 36.45 m
Finally, we shall determine the potential energy of the ball at the maximum height. This can be obtained as follow:
Mass (m) = 0.7 kg
Acceleration due to gravity (g) = 9.8 m/s²
Maximum height (h) = 36.45 m
Potential energy (PE) =?
PE = mgh
PE = 0.7 × 9.8 × 36.45
PE = 250.05 J
Thus, the potential energy at the maximum height is 250.05 J.
An object with a mass of 30 kg moves at a rate of 15 m/S over distance of 10 m. 900 joules of work was done in 10 seconds. What was the power generated by this project?
Answer:
P = 90 W
Explanation:
Mass of an object, m = 30 kg
Speed of the object, v = 15 m/s
Distance, d = 10 m
Work done, W = 900 J
Time, t = 10 s
We need to find the power generated by this project. We know that power is equal to work done divided by time taken.
So,
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{900\ J}{10\ s}\\\\P=90\ W[/tex]
So, the required power generated is 90 W.
