The linear displacement of the wheel will be 1.5m.
Linear displacement is the measure of straight path covered by the object .
Rotating angular speed of the wheel = 2.0 rad/s
Radius of the wheel = 0.25 m
According to the angular speed and linear speed relationship, we can say that linear speed is the product of angular speed and the the radius of the object
Mathematically, v = r * ωV = linear velocity
r = radius of the wheel
ω = angular velocity
V = 0.25 * 2
V = 0.5 m/s
Also, speed is equal to distance upon time.
V = d/t
Time at wheel the the wheel's linear distance is to be found = 3 s
therefore d = V * t
d = 0.5 * 3
d = 1.5 m
The linear displacement of the wheel after 3.0 s is 1.5 m.

At some point during construction, the International Space Station had a
mass of 235,565 kg. When it orbited the Earth at an altitude of 400,000 m,
what was the approximate gravitational force on the Station due to Earth's
gravity? (Recall that Earth has a radius of 6.37 × 106 m, it has a mass of 5.97
x 1024 kg, and G = 6.67 x 10-¹1 Nm²/kg².)
The gravitational force exerted on the International Space Station by the gravity of the Earth is approximately 0.00026680N.
The force of gravity, or gravitational pressure, pulls objects with mass in the direction of every other. We regularly consider the pressure of gravity from Earth. This force is what continues your body on the ground. but any object with mass exerts a gravitational force on all other items with mass.
The force of appeal on a body with the aid of earth is referred to as gravitational force. Example : The leaves and end result fall from a tree downwards closer to the ground, water in a river flows down streams, a ball thrown up goes to a peak and then returns back on floor are a few examples of motion due to gravitational force.
Earth's gravity comes from all its mass. All its mass makes a blended gravitational pull on all the mass for your body. that's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

In order to calculate the net torque for an object in static equilibrium, the pivot point __________.
In order to calculate the net torque for an object in static equilibrium the pivot point can be any convenient location.
Multiplying the moment arm by the magnitude of each force gives the magnitude of the torque due to each force. Determine whether each torque is clockwise or counterclockwise, and give each the appropriate sign when summing the torques and setting this sum to zero for balanced torque conditions.
For an object to maintain static equilibrium two equilibrium conditions must be met. First, the net force acting on the object must be zero.

If you start with 1 m naoh and 40 ml of 1 m acetic acid, how many ml of the naoh will be required to reach the equivilence point?.
There are 40 ml of NaOH will be required to reach the equivalence point.
The equivalence point is the midpoint of the vertical portion of the curve. This corresponds to a NaOH volume of 26 ml and a pH of 8.57. Half the equivalence point corresponds to a volume of 13 ml and a pH of 4.6. The titration Ka value is 4.6. No effect. The volume at the equivalence point is determined by the number of moles of acid present.
In the reaction between acetic acid and sodium hydroxide acetic acid protonates the hydroxide ion and acts as an acid. Hydroxide ions accept protons and act as bases. Equivalent points are very easy to find. Simply place the pH meter in the solution to be titrated add various volumes of titrant measure the pH and create a titration curve.

what did you observe when cart a containing added mass collided with cart b containing no mass? how does the law of conservation of momentum explain this collision?
A smaller mass coming near a larger mass will bounce back in a collision. If a larger mass is first of all moving in the direction of a smaller mass, both will preserve the momentum in the route of the preliminary momentum.
All through a collision, the full momentum of the machine of both carts is conserved due to the fact the net force on the machine is zero. If the momentum of 1 cart decreases, the momentum of the opposite cart will increase by the identical quantity.
Each cart comes toward the other in a head-on collision. If each cart has identical hundreds and speeds then they will each come to rest after they hit the Velcro pads. This collision is completely inelastic: all of the kinetic energy disappears.

Evidence of the universe's expansion comes from the Doppler redshift of light from far-off stars and galaxies (moving away from a central point). This makes the Big Bang Theory possible because, after the first "bang," all of the matter goes away from its origin.
The only procedure that we are aware of that can lengthen wavelengths occurs when the wave's origin is moving away from the observer.

after a capacitor is charged, it is removed from the power source. the separation between the plates is 4.0 mm and the electric field at a midpoint between the plates is 200 v/m. when the plates are pushed to a separation of 2.0 mm, the electric field at midpoint between the plates is:
The electric field at midpoint between the plates will be 200 v/m.
Since the capacitor is charged, it has an electric field between its plates. When the capacitor is removed from the power source, there is no longer a force pushing electrons onto one plate and off of the other, so there are still equal numbers of positive and negative charges on each plate. This means that the electric field remains unchanged from when it was fully charged.
When you push the plates together to 2 mm apart, this causes more surface area to be covered by electrons. This means that more electrons will be pushed onto one plate than off of it until they are evenly distributed across both plates again.
This means there will be more negative charge on one plate than positive charge on the other—the same way it was before you pushed them together—and therefore an increased electric field between them at midpoint between their surfaces.

The term "spectral sequence" refers to the arranging of spectral classes according to temperature.The stars classified in the previous order as "O" turned out to be the hottest, followed by "B" stars for second place and "M" stars for third place.Hence, labour of several people led to the discovery and O is the hottest, while M is the coolest is the correct option.

a wire having mass per unit length of 0.505 g/cm carries a 2.94 a current horizontally to the south. what are the direction and magnitude of the minimum magnetic field needed to lift this wire vertically upward?
The direction of the magnetic field is east and its magnitude is 0.171T.
Here we have to find the direction and magnitude of the minimum magnetic field needed.
The given values:
mass/ length (m/l) = 0.505 g/cm
Current(I) = 2.94A
Let the magnetic field be B
Formula:
Form F = I( l× B)
As it is in the south direction. So gravity is in a downward direction.
F = I( lB)
F/l = IB
F/l = mg/l
=( 0.505× [tex]10^{-3}[/tex]/ [tex]10^{-2}[/tex]) 10
=0.505
Now put in the equation we have:
0.505 = 2.94 × B
B = 0.171T in the east direction.
Therefore the direction is in the east and the magnitude of the magnetic field is 0.171T.

a baseball is thrown upward from a height of meters with an initial velocity of meters per second. determine its maximum height.
the correct answer is maximum height = 25.86 meters.
h(t) = -4.9t^2 + 8t + 3
take the derivative and set equal to zero
h'(t) = -9.8t + 8 = 0
max height is when t = 8/9.8 = 4/4.9 = about .816 seconds t
plug that value into the 1st equation above to calculate maximum height'
h(4/4.9) = -4.9(4/4.9^2) + 8(4/4.9) + 3 = -3.2653 +26.1224 +3 = 25.86 meters = max height

What is the number of paths through which electricity can flow in a series circuit?.
The correct answer is in a series circuit there will be only one path through which electricity flow.
What is series circuit or connection?
A series circuit has a channel via each component where the entire current flows.
As a result, a parallel circuit has more than one path for the current to travel while a series circuit only has one.
