How to check the speed of the object?We have a time-position graph in front of us with a few points marked on it that we ought to investigate. The location where the curve's steepest slope is located is where the object is going the fastest.The point is D in this instance.Keep in mind that the graph changes to the right; therefore, if the right side is higher than the left side at any point, the item is traveling to the left (negative x-axis) at that precise moment. In this case, the points are C, D, and E.The item accelerates when the curve's curvature changes and the slope rises; for instance, from B onwards, the acceleration increases.Next, the speed picks up at point C.

What is the name of the seismic wave that is the first to occur during an earthquake? A. S wave B. Surface wave C. P wave
P waves are first to occur during an earthquake.
There are two types of earthquake waves based on the medium of travel.
1.Body waves- these waves travel through the solid part of earth crust.
2.Surface waves- these waves travel on earth's surface.
Body waves are divided into two types of waves i.e., P waves (primary) and S waves (secondary).
1.P waves (primary waves)- these are the fastest seismic waves which travel through the earth crust. P waves are the first waves to reach any location when an earthquake occurs.
2.S waves (Secondary waves)- these waves are second fastest waves after primary waves to reach a location when the earthquake occurs. S waves have half speed than that of P waves.

The time it takes to travel 2.5cm from its mean position is 1.048 secs.
Describe the mean position.When there is no net force exerted on the body, it is in the mean position, sometimes referred to as the equilibrium position. An oscillating particle's phase: This shows how the particle is vibrating right now.
Given,
case(1), V1=4ms−1,y1=3m,
case(II), V2=3ms−1,y2=4m.
We know that, V=ω√( a^2−y^2 )
Case (I) 4=ω√(a^2−3^2)..(i)
Case(II) 3=ω√(a^2−4^2) …(ii)
Dividing (i) by (ii) , we get
16a^2−256=9a^2−81
After solving we get,
a=√25 =5m
Substituting it in (i), we get
ω= 4 / 4 = 1 rads^−1
When the particle is 2.5 meters from the extreme location, its distance from the mean position is given by the equation x = 5−2.5 = 2.5m.
Given that SHM must note the time from an extreme point, we will apply the relation:
x=acosωt.

The required electric field is 9.58 × 10⁻² N/C
We know that the electric field, E is a product of resistivity and current density
∴ E=jρ ......(i)
Where ρ⇒ Resistivity
j ⇒ Current density
j = I/A
Now, as per the question,
Resistivity of copper, ρ = 1.68 × 10⁻⁸ Ωm
Current, I = 30 ampere
Diameter = 0.259 cm = 0.00259 m
So, Radius, r = Diameter/2

An engineer wants to calculate how high a rocket starting from rest will be when it
reaches a velocity of 6,500.0 m/s with an acceleration of 389.00 m/s How the rocket be when it meets these conditions?
A moving object's speed and direction vary over time at a certain rate, which is known as acceleration. The term "acceleration" refers to the change in speed of a point or object along a straight line. Due to the constant change in direction, motion on a circle accelerates even while the speed is constant.
Velocity is measured by a specific unit of time and from a specific point of view, and it describes the rate at which an object's orientation changes while it is moving.
The term "Distance Traveled" describes how far an object has travelled during a specified amount of time to get to its destination. Or The path that a body takes to travel a specific distance at a certain speed from one location to another is known as the distance travelled.
Using,
Avg. acceleration (a) = (final velocity - initial velocity(v_i)) / time (t)
time = 6500 / 389 = 16.71 sec
Now, the following equation can be used to determine distance from acceleration: D = v*t + 1/2*a*t². where an is the acceleration, t is the passage of time, and v is the velocity.
D = distance travelled = 54309 m

they from their desk?
If the displacement of a person from their desk is 25.92 m if 27 m, 17° S of W, they are west from desk.
Resolving the 27 m distance into its horizontal and vertical components. The horizontal component will describe how far west they are and the vertical component will describe how far south they are. After resolving the components make a right angled triangle.
cos θ = Adjacent side / Hypotenuse
θ = 17°
Adjacent side = Horizontal component
Hypotenuse = 27 m
cos 17° = West distance / 27
West distance = 0.96 * 27
West distance = 25.92 m
In a right angled triangle some of the ratios similar to the one used above can be used. These ratios are called as trigonometric ratios. These ratios use trigonometric functions and relate them to sides of a right angled triangle.
