a car is accelerated from 30 mil/h to 55 mil/h during a period of 20 s. calculate the magnitude of the force exerted on the car to accelerate.
The magnitude of the force exerted on the car to accelerate is 0.5588m N
We got some values here,
v[tex]_{0}[/tex] = 30 mil/h = 13,4112 m/s
v[tex]_{1}[/tex] = 55 mil/h = 24,5872 m/s
t = 20 s
First, we should find the acceleration of the car
a = v/t
a = v[tex]_{1}[/tex] - v[tex]_{0}[/tex] / t[tex]_{1}[/tex] - t[tex]_{0}[/tex]
a = 24.5872 - 13.4112 / 20 - 0
a = 11.176 / 20
a = 0.5588 m/s[tex]^{2}[/tex]
Now we got the amount of acceleration. We can found the force by the formula of: F = m.a but we are not given the mass value in the question. So, we can answer this question by this way
F = m.a
F = m × 0.5588 m/s[tex]^{2}[/tex]
F = 0.5588m N
What is acceleration?Acceleration (a) is the change in velocity (Δv) over the change of time (Δt), represented by the equation a = Δv/Δt.

When a separate branch-circuit is run to a wall mounted oven, or to a counter-mounted cooking unit, the branch circuit size is based on of the nameplate rating of the appliance.
The ratings are shown in watts on the appliance nameplate. The circuit must be sized to provide the required number of amperes to operate the appliance at its nameplate rating.
One ampere is defined as the current that flows through a conductor when a potential difference of one volt is applied across it. The ampere is thus equivalent to the coulomb, the SI unit of charge.

Time: 10 minutes
Force:
The correct answer is 183300 Newton amount of force is needed to propel a rocket.
What connection exists between force and mass of acceleration?
Mass times acceleration, or F=m x a, equals force. This means that in order to move an object at the same speed as an object with smaller mass, a stronger force is required. Newton's Second Law of Motion is this.
Force = Mass x acceleration
Initial velocity = 11 Km/s

What is the egg's displacement?
An egg is dropped from a treehouse and takes 5 seconds to reach the ground. Air resistance can be ignored. The displacement of the egg will be 122.5m.
This question is from the branch of physics called kinematics. We use equations of motion to find out the unknown quantity from the given data. Let us use the equation of motion, s=ut+1/2*a*t²
where, s is the displacement of the egg in metres
u is the initial velocity of the egg in m/s
a is the acceleration in m/s²
t is the time in seconds
As we know that, the egg is in a freefall condition, its initial velocity is zero and acceleration is nothing but acceleration due to gravity here as it is under the action of gravity.
s=1/2*g*t²
s=1/2*9.8*5*5

an air-conditioning system requires a 20m long section of 15cm diameter duct work to be laid underwater. determine the upward force the water will exert on the duct.
The upward force the water will exert on the duct is 3.463kN.
Here we have to find the buoyancy force:
Buoyancy force:
The buoyant force is the upward force exerted on an object wholly or partly immersed in a fluid. This upward force is also called Upthrust. Due to the buoyant force, a body submerged partially or fully in a fluid appears to lose its weight, i.e. appears to be lighter.
Formula to calculate buoyancy forces:
B = ρgV
ρ= fluid density
g = acceleration due to gravity
V = fluid volume
V = πr²L
So;
B = ρgπr²L
Given data:
g = 9.8 m/s²
r = 15 cm = 0.15m
L = 20m
ρ = 1000
B = 1000× 9.8 × 22/7 ( 0.15/2)² × 20
= 3.465kN

Will Isabel's shot stop in the 10 point section of the board?
When Isabel pushes a shuffleboard disk, accelarating it to a 6,5 m/s before releasing it, the shot will stop in the 10 point section of the board.
What is the meaning of speed?The average speed is calculated by dividing the total distance traveled by the total time it took to travel that distance. Speed is the rate at which something moves at any given time. Average speed is the average rate of speed over the course of a journey. .
Velocity is the directional speed of a moving object as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard.
Since Isabel pushes a shuffleboard disk, accelarating it to a 6,5 m/s before releasing and the coefficient of kinetic friction between the disk and concrete court is 0.31, this will be illustrated thus:
The initial speed of disk = 6.5 m/s
deceleration of disk = 0.31*9.8=3.038 m/s²

The Charge on smaller of the two charges is 1.747 × 10⁻⁷ C .
When two charges come together, an attractive force occurs for opposite charges and a repulsive force for similar charges. Coulomb's law can be used to calculate the electrostatic force between two charges if the distance between them is known.
Coulomb's Law defines the following equation for this: F.E = Kₑq₁ q₂/r²
Where,
F.E --> electrostatic force in Newton
Kₑ---> Coulomb constant
q₁---> charge of the larger charge in coulombs
q₂---> charge of the smaller charge in coulombs
r ---> distance between the objects in meters
we have given that ,
charge on larger charge(q₁) = 9.56 × 10⁻⁶C
Coulomb constant (Kₑ) = 8.988×109 Nm²C⁻²
distance between two charges = 0.45 m
repulsive force between charges = 0.015 N
putting all the values in above formula we get, 0.015 = (8.988×10⁹ Nm²C⁻² × q₂ × 9.56×10⁻⁶ C)/(0.45)²

Small spherical projectiles are few shapes of the projectiles loaded for shotshells.
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
Projectile is a body projected by external force and continuing in motion by its own inertia and the velocity is constant horizontally.
Modern ammunition varies depending on the type of firearm. Rifles and handguns use a cartridge containing a single projectile (bullet). Shotguns use a shot shell containing either a single slug or a large number of small projectiles (shot or pellets). However, the basic components of cartridges and shot shells are similar. The projectile is one of them.
This projectile is similar to many. Single shot firearm is different from a repeating firearm because of the fact that the single shot firearm is in need to be reloaded each time that the single shot firearm is being used whereas the repeating firearm has extra cartilages by which it doesn't necessarily in need to be reloaded each time it has been fired.

The rate of change in the magnetic flux for the induced emf in a loop is 9.42 volts.
Magnetic flux is the number of lines of force that penetrate a plane surface perpendicularly. Meanwhile, the induced emf is the emergence of an emf on the ends of the coil caused by a change in the magnetic flux enclosed by the coil.

Initial magnetic field: Bi = 2T
Final magnetic field: Bf = 8T
The expression for the induced emf in a loop is:
ε = (dΦ/DT) → Φ = magnetic flux
ε = [tex]\frac{d(BA cos 0)}{dt}[/tex] → θ = 90°
ε = [tex]A\frac{d(B)}{dt}[/tex]

Calculation:-
Since the angle from the horizontal is Cosθ, therefore the angle from the vertical is sinθ.
Hmax = U² sin²θ/2g
11.25 = 30² sin²θ/2g
sin²θ = (11.25 × 2 × 10)/900
⇒ sin²θ = 0.25
⇒ sin θ = 0.5
⇒ sin θ = 1/2 = 30°
The horizontal pace of a projectile is regular (in no way converting in value), and there's a vertical acceleration because of gravity; its cost is 9.8 m/s/s, down, The vertical speed of a projectile changes via nine.8 m/s every second, The horizontal motion of a projectile is impartial of its vertical movement.
Projectile motion is a form of motion experienced with the aid of an object or particle that is projected in a gravitational field, such as from Earth's floor, and movements alongside a curved route below the action of gravity best.
Projectile motion is the movement of an object thrown (projected) into the air. After the initial force that launches the item, it most effectively reports the pressure of gravity. The object is known as a projectile, and its route is called its trajectory.
