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.

If the displacement of a particle is given by the formula S = 3t^3 - 20t^2 + 40t. Find (i) the displacement after 3 seconds (ii) the formula for the velocity at any time t (iii) the value of t when the particle is not moving (iv) the initial velocity of the particle (v) the formula for the acceleration at any time t (vi) the initial acceleration of the particle.
Answer:
At t = 0 S = 0
S = 3 * 3^3 - 20 * 3^2 + 40 * 3 after 3 sec
S = 3 * 27 - 20 * 9 + 120 = 21 after 3 sec
v = ds/dt = 9 * t^2 - 40 * t + 40 = 9 * 9 - 40 * 3 + 40 = 1
ds/dt = 9 t^2 - 40 t + 40 v at any time
If zero = 9 t^2 - 40 t + 40 then you need to solve the quadratic for t
a = ds^2 / dt^2 = dv /dt = 18 t - 40 for the acceleration at any time
At t = zero (the initial acceleration) a = -40
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 person lifts a 25 kg box of old sports equipment at an angle of 75 degrees to the vertical to a shelf 2.6 meters above. How much work was done by the person?
Answer:
164.87 J
Explanation:
From the question,
Work done (W) = mghcosθ........................ Equation 1
Where m = mass of the box, h = height, g = acceleration due to gravity, θ = angle to the vertical
Given: m = 25 kg, h = 2.6 meters, θ = 75°.
Constant: g = 9.8 m/s²
Substitute these value into equation 1
W = 25×9.8×2.6×cos75°
W = 164.87 J.

In the following figure, a table of mass 0.44 Kg is pushed against an inclined surface with a 15 inclination angle. Find the amount of the horizontal component of the Weight
Answer:
W = 1.11 N
Explanation:
Given that,
Mass of a table, m = 0.44 kg
It is pushed against an inclined surface with a 15 inclination angle.
We need to find the amount of the horizontal component of the weight. The horizontal component of weight is given by :
[tex]W=mg\sin\theta\\\\W=0.44\times 9.8\times \sin(15)\\\\W=1.11\ N[/tex]
So, the amount of the horizontal component of the weight is 1.11 N.
Electric current flows through paths called circuits. People often build circuits using wires, resistors, and batteries. A battery is a voltage source.
A circuit with which components has the highest current with the given voltages?
wires, a 9V battery, no resistors
wires, a 9V battery, a light bulb
wires, a 1.5V battery, no resistors
wires, a 1.5V battery, a light bulb
Answer:the answer is A. Wires, a 9v battery, no resistors
Explanation:
A wire with battery of the voltage of 9 volts with no resistor has the highest value of current. The ampere is the SI unit for electric current.
What is electric current?The pace at which electrons travel through a conductor is known as electric current. Electrons are tiny particles that reside within a substance's molecular structure.
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
The Equation of Ohm's Law
V=IR
If there is no resistor, the resistance in the circuit is zero, results in the highest value of electric current.
Voltage is directly proportional to the current. As high the value of voltage, the value of the electric current is high.
Hence, a wire with battery of the voltage of 9 volts with no resistor has the highest value of current.

Calculate the energy absorbed when 13 kg of liquid water raises from 18°C to 100°C and then boils at 100°C.
Answer:
the energy absorbed is 4.477 x 10⁶ J
Explanation:
mass of the liquid, m = 13 kg
initial temperature of the liquid, t₁ = 18 ⁰C
final temperature of the liquid, t₂ = 100 ⁰C
specific heat capacity of water, c = 4,200 J/kg⁰C
The energy absorbed is calculated as;
H = mcΔt
H = mc(t₂ - t₁)
H = 13 x 4,200(100 - 18)
H = 4.477 x 10⁶ J
Therefore, the energy absorbed is 4.477 x 10⁶ J

Which statement best explains the difference between light waves traveling through a vacuum and light waves traveling through a medium?
Answer:
The statement which best explains the difference between the light waves travelling through a vaccuum and light waves travelling through a medium is -"When light waves travel through a vacuum, they travel faster than when they travel through a medium."
Explanation:
Light waves are faster in vacuum because The refractive index of vacuum is the lowest since there is no barrier in the way of light propagation in vacuum. Demonstrate that the maximum speed of light in vacuum.
In a vacuum, light flies at 186,283 mph. Light flies at 186,200 mph in the air, or 56 mph slower. In another medium, such as water, light travels at 139,712 mph, or around 3/4 of the speed of light in a vacuum.
LIGHT WAVES -: Light waves are a form of electromagnetic wave that includes both visible and invisible to the naked eye wavelengths on the electromagnetic spectrum. The average human eye can see light with wavelengths ranging from 390 to 700 nanometers, or nm.
Forms of light waves comprises of Radio waves , microwaves , infrared waves , visible light etc.
When light waves travel through a vaccume, they travel faster than when they travel through a medium
What is light wave?A light wave is an electromagnetic wave which travels through the vacuum of outer space. Light waves are produced by vibrating electric charges., An electromagnetic wave is a transverse wave which has both an electric and a magnetic component.
Light waves are faster in vaccum because the refractive index of vaccume is the lowest since there is no barrier in the maximum speed of light in vaccum.
In vaccum light travels at 186283 mph in air 186200 mph in other medium like water at 139712 mph.
Hence light waves travel through a vaccum, they travel faster than when they travel through a medium

What is gravity?
Answer:
An invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. ... Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.

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
