device based on atmospheric pressure
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.

stay safe healthy and happy.A small canon is placed on top of a fortification the cannon ball leaves the muzzle of the canon with a speed of 85 m/s
Answer:
Speed of cannonball just before it hits the ground is 90.77 m/s
Explanation:
Complete Question
A small cannon is placed on top of a fortification. the cannonball leaves the muzzle of the cannon with a speed of 85 m/s at an angle of 25°c above the horizontal. just before the cannonball hits the ground, the vertical component of velocity is 48 m/s downward. what is the speed of the cannonball just before it hits the ground? ignore air resistance.
Solution
Given
Speed = 85 m/s
The angle = 25 degrees
When it will hit the ground, then vertical velocity = 48 m/s
However, in the projectile motion, the horizontal component will not change
Vr = V cos (theta) = 85 * cos25
Speed of cannonball just before it hits the ground is
V’ = Sqrt (48^2 + (85 * cos 25)^2) = 90.77 m/s
Determine the amount of electrical energy (in J) used by the following devices when operated for the
indicated times.
c. X-Box video game player (180 W) - operated for 2 hours
d. 42-inch LCD television (210 W) - operated for 3 hours
Answer:
Find answers below.
Explanation:
Given the following data;
c. Power = 180 Watts
Time = 2 hours = 60*60*2 = 7200 seconds
To find the energy used;
Energy = power * time
Energy = 180 * 7200
Energy = 1296000 Joules
d. Power = 210 Watts
Time = 3 hours = 60*60*3 =
Energy = 210 * 10800
Energy = 2268000 Joules

Answer:
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
Wavelength can be defined as the distance from one peak to the next peak. Also, this distance is equal to the distance from one trough of a wave to another.
Mathematically, the speed of a wave is given by the formula;
V = fλ
Where;
V is the speed of the wave.
f is the frequency of the wave.
λ is the wavelength of the wave.
The speed of a wave (wave speed) is directly proportional to the frequency of a wave.
This ultimately implies that, an increase in the speed of a wave would cause an increase in the frequency of a wave and vice-versa.

Answer:
need Read this excerpt from "Not a Dove, But No Longer a Hawk."
Despite these misgivings, I do not see how we can do anything but continue to prosecute the war. We can and should limit the violence and the suffering being inflicted on the civilians as much as possible, but for whatever reasons, successive Administrations in Washington have carried the commitment in Vietnam to the point where it would be very difficult to prevent any precipitate retreat from degenerating into a rout. If the United States were to disengage from Vietnam under adverse conditions, I believe that the resulting political and psychological shockwaves might undermine our entire position in Southeast Asia.
Which statement best describes the paradox in this excerpt?
The author acknowledges that civilians should not suffer, but states that the civilians must retreat.
The author suggests that the administrators in Washington are busy making policies while overlooking the need to end the war.
The author acknowledges that the violence should stop, but admits that a retreat might have dire consequences.
The author suggests that the Vietnamese people are counting on US support, though their political ideals are not democratic.

The rate at which charge passes through a 6 Ω resistor at a given point in time is 3 mA. How much charge passes through this resistor in 5 seconds?
Answer:
Q = 0.015 Coulombs
Explanation:
Given the following data;
Resistance = 6 Ω
Current = 3 mA = 0.003 A
Time, t = 5 seconds
To find the quantity of charge passing through the resistor;
Mathematically, quantity of charge is given by the formula;
Quantity of charge, Q = current * time
Q = 0.003 * 5
Q = 0.015 Coulombs
A 650 × 10–4 F capacitor stores 24 × 10–3 of charge. What is the potential difference between the plates?
Answer:
0.369 V
Explanation:
Given :
Capacitance ( c ) = 650 × 10–4 F
Charge ( q ) = 24 × 10–3 C
We are asked to find potential difference ( v )!
We know:
q = c v
= > v = q / c
Putting values here we get:
= > v = ( 24 × 10–3 ) / ( 650 × 10–4 ) V
= > v = 240 / 650 V
= > v = 24 / 65 V
= > v = 0.369 V
Therefore, potential difference between the plates is 0.369 V

Which equations are equivalent to 3/4+m=-7/4? Select three options.
M= 10/4
M=-10/4
M=-5/2
11/4+m=-1/4
-5/4+m=-15/4
Answer:
M= -10/4
M = -5/2
-5/4 + m = -15/4
Explanation:
3/4 + m = -7/4
Subtract 3/4 from both sides
3/4 + m - 3/4 = -7/4 - 3/4
m = (-7-3) / 4
m = -10/4
m = -5/2
Check the options
11/4 + m = -1/4
m = -1/4 - 11/4
m = (-1-11) /4
m = -12/4
m = -3
-5/4 + m = -15/4
m = -15/4 + 5/4
m = (-15+5) /4
m = -10/4
m = -5/2

Explanation:
Upon collision, the clay and steel block stick together and move to the right with a speed of 1.5m/s.
What is conservation of momentum principle?When two bodies of different masses move together each other and have head on collision, they travel to same or different direction after collision.
The external force is not acting here, so the initial momentum is equal to the final momentum. For inelastic collision, final velocity is the common velocity for both the bodies.
m₁u₁ +m₂u₂ =(m₁ +m₂) v
Substitute the values for m₁ = 3kg, m₂ =1kg, u₁ =0 and u₂ =6 m/s, then the final velocity will be
3x0 +1x6 = (3+1)v
v = 1.5 m/s
Thus, the clay and steel both have final velocity is 1.5 m/s.

what are the variables in an experiment that tests the distance honey flows at different temperatures? identify the independent variable (the one we can control) and the dependent variable (the one we cannot control).
Answer:
The distance that the honey flowed would be the dependent or outcome variable and the temperature of the honey would be the independent variable.
The dependent variable is what is being measured in an experiment. You can remember it by thinking “it depends on what you’re changing.”
The independent variable in an experiment is what is being changed. You can remember this by thinking “the Independent variable is what I as the scientist change.”
Explanation:

The machine in the figure is ideal and an effort force of
7.0 N just lifts a 14.0 N box situated 0.75 m from the
pivot, what is the distance from the pivot point to
where the effort force is exerted?
Answer:
1.5 m
Explanation:
Let the distance from the box to the pivot be c.
Let the distance from the pivot to the effort be y.
From the question given above, the following data were obtained:
Effort force (Fₑ) = 7 N
Force of resistance (Fᵣ) = 14 N
Distance from the box to the pivot (c) = 0.75 m
Distance from the pivot to the effort (y) =?
Clockwise moment = Fₑ × y
Anticlock wise moment = Fᵣ × c
Clockwise moment = Anticlock wise moment
Fₑ × y = Fᵣ × c
7 × y = 14 × 0.75
7 × y = 10.5
Divide both side by 7
y = 10.5 / 7
y = 1.5 m
Therefore, the distance from the pivot to the effort is 1.5 m
