A 2 N and an 8 N force pull on an object to the right and a 4 N force pulls to the left a 0.5 kg object. What is the acceleration on the object?
Answer:
Acceleration is 12m/s^2
Explanation:
We have a resultant force of 10N to the right and a resultant of 4N to the left, since the tow forces are acting in opposite directions, we subtract the two forces to find the net force. The net force would be 6N to the right.
We also know that F=ma, where F=force, m=mass, and a=acceleration
we can rearrange the equation like this,
a=F/m
now we can plug in the known variables
a=6N/0.5kg
a=12m/s^2
The acceleration of the object will be 12 m/s² towards the right.
We have two forces acting in opposite direction.
We have to determine the acceleration of object.
What is Acceleration ?The rate of change of velocity with time is called Acceleration.
a = dx/dt
According to the question -
F [1] = 2 aₓ
F [2] = 8 aₓ
F [3] = - 4 aₓ
Mass (m) = 0.5 Kg
now, according to the question -
Net force (F) = F [1] + F [2] + F [3] = 2 aₓ + 8 aₓ - 4 aₓ = 6 aₓ
| F | = 6 N
Therefore -
F = ma
a = F/m
a = 6/0.5 = 12 m/s²
Hence, the acceleration of the object will be 12 m/s² towards the right.

Explanation:
An object is accelerating at 15 m/s^2 with a mass of 4 kg on it. What is the resulting force on this object?
Answer:
60 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 4 × 15
We have the final answer as
60 NHope this helps you

a 0.3 kg arrow is fired from a bow with a kinetic energy of 82.0 J. what is its velocity?
Answer:
When the string of a bow and arrow is pulled from equilibrium, the elastic potential energy in the bow is converted to kinetic energy of the arrow when the string is released.
Kinetic energy of an arrow can be found by using the formula KE=(mv²)/450,240 where m = mass of the arrow in grains and v = velocity of the arrow in fps.
Two factors determine the amount of energy a bow can hold. Its draw weight is the amount of force required to draw the bow. A bow's draw weight increases the farther back you pull the string.
Does a stretched bow and arrow have energy?
An arrow held in a stretched bow also contains this stored energy. Specifically, the bow has elastic potential energy. When the bow is released, the arrow will move. ... When work is done on an object, the work may be converted into either kinetic or potential energy.

what is a quantity such as mass, length, or speed which is completely specified by its magnitude and not direction called?
Answer:
Scalar quantity
Explanation:
Scalar quantities are measurements that consist of only a magnitude which is measured in numbers only. For example speed is a magnitude because it measures how fast something is going.
Vector quantities are measurements that include a magnitude and direction which means there is a number measurement and a direction associated with that measurement. For example, velocity is a vector quantity because there is a measurement of speed, and it also includes the direction of the speed.

wo ships, one 200200 metres in length and the other 100100 metres in length, travel at constant but different speeds. When travelling in opposite directions, it takes 1010 seconds for them to completely pass each other. When travelling in the same direction, it takes 2525 seconds for them to completely pass each other. The speed of the faster ship, in metres per second, is
Answer:
The speed of the faster ship is 22.5 m/s
Explanation:
The length of the ships are;
Ship 1 = 200 m
Ship 2 = 100 m
The time it takes for the ships to completely cross each other when travelling in opposite directions = 10 seconds
The time it takes both ships to cross each other when travelling in the same direction = 25 seconds
Let x represent the speed of the first ship, ship 1, and y represent the speed of the second ship, ship, 2, we have;
(x + y) × 10 = 200 + 100 = 300
10·x + 10·y = 300...(1)
(x - y) × 20 = 200 + 100 = 300
20·x - 20·y = 300...(2)
Multiply equation (1) by 2, to get;
(x + y) × 10 × 2 = 300 × 2
20·x + 20·y = 600...(3)
Adding equation (1) to equation (3) gives;
20·x + 20·y + 20·x - 20·y = 600 + 300
40·x = 900
x = 900/40 = 22.5
x = 22.5
The speed of the first ship, ship 1 = x = 22.5 m/s
From equation (1), we have;
10·x + 10·y = 300
y = (300 - 10·x)/10 = (300 - 10×22.5)/10 = 7.5
y = 7.5
The speed of the second ship, ship 2 = y = 7.5 m/s
Therefore, the faster ship is ship 1 with a speed of 22.5 m/s

What is the latent heat of vaporization for water
When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation.
