In the picture above, if the cue stick strikes the 0.2-kg cue ball with a force of 1.1 N, what will be the acceleration of the cue ball?
Answer:
0.55 m/s².
Explanation:
From the question given above, the following data were obtained:
Mass (m) of ball = 2 Kg
Force (F) applied = 1.1 N
Acceleration (a) =?
Force (F) is defined as the product of mass (m) and acceleration (a). Mathematically, the force (F) can be represented as:
Force (F) = mass (m) × acceleration (a)
F = ma
With the above formula, we can calculate the acceleration of the ball as follow:
Mass (m) of ball = 2 Kg
Force (F) applied = 1.1 N
Acceleration (a) =?
F = ma
1.1 = 2 × a
Divide both side by 2
a = 1.1 / 2
a = 0.55 m/s²
Therefore, the acceleration of the ball is 0.55 m/s²
a catcher "gives" with the ball when he catches a 0.196 kg baseball moving at 31 m/s. if he moves his glove a distance of 5.32 cm, what is the average force acting on his hand?
Answer:
3540.5N
Explanation:
Step one:
given data
mass m= 0.196kg
speed v= 31m/s
distance r= 5.32cm = 0.0532m
Step two
The expression relating force, mass, velocity and distance is
F= mv^2/r
substitute we have
F=0.196*31^2/0.0532
F=0.196*961/0.0532
F=188.356/0.0532
F=3540.5N

Answer:
i) 2Mg + O₂ + Δ Heat → 2MgO + Δ Energy
ii) The aqueous solution does not change in the color of the blue litmus paper and the blue litmus paper remains blue in color
The aqueous solution formed using the product (MgO) turns the red litmus paper blue
Explanation:
i) Magnesium easily burns in air or oxygen when heated to form a white powder of magnesium oxide. The burning (reaction) of magnesium in air is an exothermic reaction that involves the release of heat and light
The burning of magnesium wire is given by the following chemical reaction;
2Mg + O₂ + Δ Heat → 2MgO + Δ Energy
ii) When magnesium oxide is mixed with water if forms magnesium hydroxide Mg(OH)₂ as shown in the following chemical reaction;
MgO + H₂O → Mg(OH)₂
Magnesium hydroxide is basic and therefore it will turn red litmus paper blue and it does not change the color of the blue litmus paper.

Which circuit shows three resistors connected in series?
The circuit shows three resistors connected in series is the letter B because he elements are connected on the same wire and there is only one path for the electric current to flow.
What is the difference between series and parallel circuit?The main difference between series and parallel circuit is the way voltage and current are presented. The voltage will be the same at all points in the parallel circuit and the current will vary. In series circuit, it is the voltage that can be different, while the electric current is the same.
In a series electric circuit, the elements are connected on the same wire and there is only one path for the electric current to flow. For this reason, the electric current is the same in all elements of the circuit.

fits tightly inside an aluminium tube whose internal diameter is 8mm at
0
0C. When the temperature is raised, the fit is no longer exact. Calculate
what change in temperature is necessary to produce a channel whose
cross-section is equal to that of a tube of 1mm internal diameter. (linear
expansivity of silica = 8X10-6
/K and linear expansivity of aluminium =
26X10-6
/K )
Correct question is;
A thermal tap used in a certain apparatus consists of a silica rod which fits tightly inside an aluminium tube whose internal diameter is 8mm at 0°C.When the temperature is raised ,the fits is no longer exact. Calculate what change in temperature is necessary to produce a channel whose cross-sectional is equal to that of the tube of 1mm. (linear expansivity of silica = 8 × 10^(-6) /K and linear expansivity of aluminium = 26 × 10^(-6) /K).
Answer:
ΔT = 268.67K
Explanation:
We are given;
d1 = 8mm
d2 = 1mm
At standard temperature and pressure conditions, the temperature is 273K.
Thus; Initial temperature; T1 = 273K,
Using the combined gas law, we have;
P1×V1/T1 = P2×V2/T2
The pressure is constant and so P1 = P2. They will cancel out in the combined gas law to give:
V1/T1 = V2/T2
Now, volume of the tube is given by the formula;V = Area × height = Ah
Thus;
V1 = (πd1²/4)h
V2 = (π(d2)²/4)h
Thus;
(πd1²/4)h/T1 = (π(d2)²/4)h/T2
π, h and 4 will cancel out to give;
d1²/T1 = (d2)²/T2
T2 = ((d2)² × T1)/d1²
T2 = (1² × T1)/8²
T2 = 273/64
T2 = 4.23K
Therefore, Change in temperature is; ΔT = T2 - T1
ΔT = 273 - 4.23
ΔT = 268.67K
Thus, the temperature decreased to 268.67K
Question 3 of 10
Which law is stated below?
The acceleration of an object is proportional to the force applied to it and
inversely proportional to its mass.
A. The law of inertia
B. Newton's first law
C. Newton's third law
D. Newton's second law
Answer:
D. Newton's second law
Explanation:
Newton's second law of motion states that force of an object is a product of its mass and its acceleration.
Mathematically, F= ma where m is mass and a is acceleration
So from the statement above : The acceleration of an object is proportional to the force applied to it and inversely proportional to its mass , it can be seen from the formula variation as;
F= ma -----making a the subject of the formula
a= F/ m
a= 1/m * F --------- a is inversely related to m as you can see from 1/m but directly related to F hence;
Increase in mass with the same force applied causes the body to accelerate slower where as when force increases, the body accelerates faster.

Explanation:
Glider A of mass 0.355 kg moves along a frictionless air track with a velocity of 0.095 m/s. It collides with glider B of mass 0.710 kg moving in the same direction at a speed of 0.045 m/s. After the collision, glider A continues in the same direction with a velocity of 0.035 m/s. What is the velocity of glider B after the collision?
Answer:
vB' = 0.075[m/s]
Explanation:
We can solve this problem using the principle of linear momentum conservation, which tells us that momentum is preserved before and after the collision.
Now we have to come up with an equation that involves both bodies, before and after the collision. To the left of the equal sign are taken the bodies before the collision and to the right after the collision.
[tex](m_{A}*v_{A})+(m_{B}*v_{B})=(m_{A}*v_{A'})+(m_{B}*v_{B'})[/tex]
where:
mA = 0.355 [kg]
vA = 0.095 [m/s] before the collision
mB = 0.710 [kg]
vB = 0.045 [m/s] before the collision
vA' = 0.035 [m/s] after the collision
vB' [m/s] after the collison.
The signs in the equation remain positive since before and after the collision, both bodies continue to move in the same direction.
[tex](0.355*0.095)+(0.710*0.045)=(0.355*0.035)+(0.710*v_{B'})\\v_{B'}=0.075[m/s][/tex]
Which statement about the relationship between air pressure and air density is accurate?
A) Air pressure decreases as air density increases
B) Air pressure increases as air density increases
C) Air pressure increases as air density decreases
D) Air pressure is unrelated to air density
Answer:
A: Air pressure decreases as air density increases
Explanation:
Pressure is a force exerted on or against an object by being in contact with a substance. Thus, air pressure is due to the bombardment of the air (gas) particles with a surface. Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume.
If that Explanation does not make any sense let me make it easier.
The air at the top of a mountain is cooler than the air at the bottom. This temperature difference is due to a phenomenon that occurs in Earth’s atmosphere. Air rises and sinks based on differences in temperature and pressure. Here’s a quick experiment that will help explain the role of pressure.Take in a deep breath as if you were ready to blow out birthday candles. Puff your cheeks with air like a chipmunk. Hold it for a few seconds, and then blow the air slowly from your cheeks.Cold air sinks while warm air rises because cold air is denser than warm air. When a lot of cold air sinks, it creates an area of high air pressure where it hits the surface. This high-pressure air flows to an area of low pressure, creating wind. When this air warms, it rises up into the atmosphere.Temperature decreases as altitude increases. That’s why a mountain peak may be covered with snow while the bottom of the mountain is full of green plants and trees. When warm air rises into the atmosphere, it cools. The density of the air increases as it cools, which eventually creates an area of high pressure and starts the cycle again.
If not for this phenomenon of air rising and sinking in the atmosphere, there would be no wind or weather.
I hope that helped!
