A 90N force towards postive x-axis, A 50N force towards negative x-axis applied on 5kg object. Find:- A) the net force on the object and B) the acceleration of the object
Answer:
a. Net force = 40 Newton.
b. Acceleration = 8m/s²
Explanation:
Given the following data;
Force on postive x-axis = 90N
Force on negative x-axis = 50N
Mass = 5kg
a. To find the net force;
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
The net force is equal to the difference between the two forces applied because they are acting in opposite directions.
Net force = 90 - 50
Net force = 40N
b. To find the acceleration;
Acceleration = net force/mass
Acceleration = 40/5
Acceleration = 8m/s²

A 9 kg blob moving at 5 m/s collides and sticks to a second blob with a mass of 5 kg. If the two bobs stick together, what will the velocity of the two blobs move at?
Answer:
the final velocity of the two blobs after collision is 3.21 m/s.
Explanation:
Given;
mass of first blob, m₁ = 9 kg
mass of the second blob, m₂ = 5 kg
initial velocity of the first blob, u₁ = 5 m/s
initial velocity of the second blob, u₂ = 0
Let the final velocity of the two blobs after collision = v
Apply the principle of conservation linear momentum to determine v;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
9 x 5 + 5 x 0 = v(9 + 5)
45 = 14v
v = 45 / 14
v = 3.21 m/s
Therefore, the final velocity of the two blobs after collision is 3.21 m/s.
A 6.3 μC electric charge is placed in an Electric Field with a magnitude of 5.0 x 105 charge due to the Electric Field? N/C. What is the electric force on the charge due to the electric field
Answer:
F = 3.15 N
Explanation:
Given electric charge, q = 6.3 μC
The magnitude of electric field, [tex]E=5\times 10^5\ N/C[/tex]
We need to find the electric force on the charge due to the electric field. The electric force is given by :
F = qE
Putting all the values,
[tex]F=6.3\times 10^{-6}\times 5\times 10^5\\\\F=3.15\ N[/tex]
So, the required force on the charge is 3.15 N.
Which way does electricity flow?
Answer: in an electrical circuit, electricity flows one direction: out of the positive terminal of a battery and back into the negative terminal.
Explanation:
Answer:
one direction: out of the positive terminal of a battery and back into the negative terminal.
Explanation:
Electrical engineers say that, in an electrical circuit, electricity flows one direction: out of the positive terminal of a battery and back into the negative terminal. Electronic technicians say that electricity flows the other direction: out of the negative terminal of a battery and back into the positive terminal.

Explanation:
7.Conduction
Assuming the pot is cold and the heating element is hot: Heat will be transferred from the element to the pan via conduction because they are in contact with one another.
8. C The moon
9. A heat, light and sound energy.
When fireworks explode, chemical energy is transformed into thermal energy, mechanical energy, radiant energy, and sound energy.
10.A 70% light energy, 30% thermal energy
When the flashlight is turned on, the chemical energy is first transformed into electrical energy and then into light energy.
If number 10 is not correct then the answer is C.
Why does it take a long time for a train to come to a complete stop?
A. unbalanced forces
B. balanced forces
C. inertia
Answer:
Intertia
Explanation:
Interia is like a property in whichit continues in its existing state of (rest or uniform motion ) in a straight line, unless that state is changed by an external force.
But
Balanced forces is just when two forces act on an onject and the net force is zero. Inshort it doesnt hve any affect on the object.
Unbalanced forces is just when two forces act on an onject and the net force is NOT zero. Inshort it does hve any affect on the object.

an object is realsed From rest . how far does it fall during the second second of fall?
Answer:
14.715 m
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards, take downwards as positive
First second:
v = u + at
v = 9.81 m/s
Second second:
s = ut + (1/2)at^2
s = 9.81(1) + (1/2)(9.81)(1)^2
s = 14.715 m

Does someone know how to do math with that equation
Answer:
f = 5 cm
Explanation:
using the thin lens equation, given as follows:
[tex]\frac{1}{f} = \frac{1}{d_{o}}+\frac{1}{d_{i}}\\[/tex]
where,
f = focal length = ?
do = the distance of object from lens = 20 cm
di = the distance of image from lens = 6.6667 cm
Therefore,
[tex]\frac{1}{f} = \frac{1}{20\ cm}+\frac{1}{6.6667\ cm}\\\\\frac{1}{f} = 0.199999\ cm^{-1}\\\\f = \frac{1}{0.199999\ cm^{-1}}\\\\[/tex]
f = 5 cm
This graph shows a supply curve. A graph titled Supply Curve has Quantity Supplied on the x-axis, from 0 to 50 in increments of 10, and price on the y-axis, from 0 to 15 dollars in increments of 5 dollars. A line is drawn with points (10, 5 dollars), (20, 7 dollars), (30, 10 dollars), (40, 13 dollars), and (40, 15 dollars). What happens when the price of a good increases? The quantity of goods that are produced increases. The producer of the good is certain to make less money. The quantity of goods that are produced decreases. The quantity of goods that are produced stays about the same.
Answer:
A just took the quiz on edge
Explanation:
In the supply curve, when the price of a good increases, A. The quantity of goods that are produced increases.
What is supply?Supply simply means the quantity of goods and services that a supplier is willing to sell at a particular place, price and time.
In this case, when there's an increase in the price of goods, it should be noted that producers will supply more of the goods. This is done in order to generate more revenue.

A hydraulic jack has an output piston
of area 0.100 m2. A 55.8 N input force
creates 419 N of output force. What is
the area of the input piston?
Answer:
Explanation:
You want the area of the output piston not the input piston. The input piston creates a pressure equal to
55.8 N/0.1 m^2 = 558 N/m^2. This pressure is transmitted through the hydraulic fluid and applied to the output piston. The pressure exerted on the output piston is equal to 419 N/Am^2. Set this equal to the applied pressure and solve for A, the area of the output piston.
419/A = 558 , A = 419/558 = 0.751 m^2
Answer:
0.0133 m^2
Explanation:
55.8/419=0.133
0.133*0.100= 0.0133

Dos cargas puntuales se localizan en el eje +X de un sistema de coordenadas. La carga q1= 1nC esta a 2cm del origen y la carga q2= -3 nC esta a 4cm del origen. ¿cual es la fuerza tras que ejercen estas dos cargas sobre una carga q3= 5nC que se encuentra en el origen?
Answer:
F_net = 1.125 10⁻⁶ N
positive direction of the x axis
Explanation:
The electric force is given by Coulomb's law
F =[tex]k \frac{q_1q_2}{r_{12}^2}[/tex]
also used charge of equal sign repel each other.
We appease this information to our problems
the charge q₁ is positive and the charge q₃ is positive for which the force is repulsive; ; a charge q₂ is negative so the force is attractive.
If we apply that the forces are vectors
F_net = - F₁₃ + F₂₃
F_net = [tex]-k \frac{q_1q_3}{r_{13}^2} + k \frac{q_2q_3}{r_{23}^2}[/tex]
F_net = k q₃ ( [tex]- \frac{q_1}{r_{13}^2} + \frac{q_2}{r_{23}^2}[/tex] )
let's look for the distances
r₁₃ = 2-0 = 2 cm = 2 10⁻² m
r₂₃ = 4-0 = 4 cm = 4 10⁻² m
let's substitute
F_net = 9 10⁹ 5 10⁻⁹ ( [tex]- \frac{1 \ 10^{-9}}{2 \ 10^{-2}} + \frac{3 \ 10^{-9}}{4 \ 10^{-2}}[/tex])
F_net = 45 (- 0.5 10⁻⁷ + 0.75 10⁻⁷)
F_net = 1.125 10⁻⁶ N
the positive sign indicates that the outside has a positive direction of the x axis, that is, it is to the right
