The maximum static friction that could be exerted on the crate is 58.8.

Static friction is a force that keeps an object at rest. Friction is experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface on which it is on.

Formula for static friction:

Static friction(max) = Normal force × Static friction

= mg × μ

m = mass = 10kg

g = gravity on the body = 9.8 m/s²

μ = static friction = 0.60

Now putting these values in the equation, we get:

Static friction = 10 × 9.8 × 0.60

                     = 58.8

Therefore the static friction is 58.8.

The crane does increase the kinetic and potential energy of the beam: W=ΔK+ΔU. Potential energy fluctuates with height while kinetic energy changes with speed W=mΔv2/2+mgΔh.

We should figure out v before moving on. We are aware that the beam is moving 95 meters away at an acceleration of 1.8 text m/s/s. Assuming that the acceleration is uniform and that the initial velocity was 0 m/s.

v2f=v2i+2aΔx

v2f=(0 m/s)

2+2(1.8 m/s2)(95 m) (95 m)

v2f=342 m2/s2 (saving one additional sign. for calculations in the future)

vf=18.5 m/s

Now that we are aware of acceleration vf and v, we may proceed to calculate W.

W=mΔv22+mgΔh

W=m(Δv22+gΔh)

W = 425 kg((18.5 m/s)22+(9.81 m/s2)(95 m))+(9.81 m/s2)

W=(425 kg)(171 + 932 m2/s2)

The velocity of the plane is 120 km/hr.

Velocity is the pace at which an object's location is changing as perceived from a particular point of view and as measured by a certain unit of time (for example, 60 km/h northbound). Velocity is the direction at which an object is traveling. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that deals with the motion of bodies. In order to be defined, the physical vector quantity known as velocity needs to have both a magnitude and a direction. Speed is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI. Speed is the scalar absolute value (magnitude) of velocity (metric system). As opposed to "5 meters per second east," which is a vector, "5 meters per second," for instance, is a scalar.

Distance traveled = 360 km

Time taken = 3 hours

Hence, velocity = 360/3 = 120 kmph

The acceleration vector will be the vector sum of the tangential and radial acceleration components because the train is changing both its speed and direction.

Since the train is altering both its speed and direction, the vector sum of the tangential and radial acceleration components will represent the acceleration vector.

The radius of curve and the train's speed can be used to calculate the tangential acceleration, while the elapsed time and changing speed can be used to calculate the radial acceleration.

Let's first convert the speed measurements from km/h to m/s:

v I = 90.0 km/h

= (90.0 km/h) (10 3 m/km) (1 hour and 36 minutes)

= 25.0

m/s v f = 50.0 km/h

= (50.0 km/h) (10 3 m/km) (1 hour and 36 minutes)

= 13.9 m/s

Backwards, the tangential acceleration is equal to a t = t v = 15.0s (13.9 m/s 25.0 m/s = 0.741 m/s 2), and the radial acceleration is equal to a r = r v 2.

The angle of refraction for the light ray with the wavelength of 589nm traveling through air strikes a crown glass at 30.0° incidence is 19.2°.

Refraction is the quantity used to measure the amount of refraction taking place at any boundary when light passes between the two mediums.

Refractive index can be calculated using Snell's law, the formula for calculating angle of refraction is as follows:

n₁/n₂ = sinФ₁/sinФ₂

n₁. sin(i) = n₂. sin(r)

where, n₁ = refractive index of medium 1

n₂ = refractive index of medium 2

i = angle of incidence in air

r = angle of refraction in glass

Therefore, by putting the values in this formula we can get the angle of refraction.

Energy becomes half i.e. E' = E/2 if the distance between the plates is doubled.

Let's say the area of parallel plates = A

The distance between plates = d

The potential difference between Plates = V

Now, the capacitance is given by

If the separation between the plates is doubled then the value of capacitance will become half.

Because of this, it turns out that gravity does not matter when we compare the distance traveled by objects with different masses. The important part of the force is air resistance also called drag.
