A 15 kg box sits still on a rough inclined plane (no math required here).

Why isn’t the box sliding down the hill?

Answer:

0.2m

Explanation:

F = 6 x 10^3N

k = 3 x 10^4 Nm-1

x = ?

from Hooke's law, F = kx

x = F/k = 6 x 10^3 ÷ 3 x 10^4 = 0.2m

Answer:

The answer is weight.

Mass is constant, your mass, height and width won’t change. So that leaves weight.

50.37 m/s and 40ms object

Answer:

They transfered more energy in the morning.

Explanation:

This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with  the waves. They have more energy, so they can crash aganst the shore more!

Answer:

Velocity because it has both magnitude (10m/s) and direction (to the ground).

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

In this scenario, an eagle flying 10 meters per second swoops down to the ground to catch a snake. Therefore, this is an example of velocity.

Answer:

velocity= 135m/s

Explanation:

velocity = 300×0.45

= 135m/s²

Answer:

As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. ... Thus, entropy measurement is a way of distinguishing the past from the future.

Explanation:

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Explanation:

α=30°

F=20 N

Fh=F*cos(α)

Fv=F*cos(90-α)=F*sin(α) (vertical component of the force F)

Fv=20*0,5=10.00 N

Answer:

Liquid

Explanation:

Thw answer is liquid

Answer:

t= 80 seonds

Explanation:

Given that,

The average velocity of Ranjana, v = 3.2 m/s

We need to find how long does she take to cover a displacement  of 256 m. Let she takes t time.

We know that,

Average speed = distance/time

So,

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{256\ m}{3.2\ m/s}\\\\t=80\ s[/tex]

So, she will take 80 seconds to cover a displacement of 256 m.

F = 6.0 x 10⁻⁸ N

Given

mass of 2 dump trucks = 1500 kg

distance = 50 m

Required

Gravitational force

Solution

Newton's Gravity Law:  

[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]

with F = gravitational force,  

G = gravitational constant,  

m1, m2 = mass of object,  

r = distance between two objects.  

Input the value :

F = (6.67.10⁻¹¹N.m² / kg² x 1500²) :  50²

F = 6.0 x 10⁻⁸ N

The Right Hand Rule, illustrated at left, simply shows how a current-carrying wire generates a magnetic field. ... The Left Hand Rule shows what happens when an electrical current enters a magnetic field. You need to contort your hand in an unnatural position for this rule, illustrated below

Answer:

50 x 3000 = 150000/4000 = 37.5

37.5 I think.

Explanation:

A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles together, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

We may use the concept of conservation of momentum to calculate the final velocity of the two vehicles after the collision.

The total initial momentum (P_initial) is given by:

P_initial = (mass of truck) * (initial velocity of truck) + (mass of car) * (initial velocity of car)

P_initial = (3000) * (50) + (1000) * (0)

The velocity:

Vt = 50 * (1000/3600) = 13.9 m/s

Vc = 0 = 0 m/s

P_initial = (3000) * (13.9) + (1000) * (0 )

P_initial = 41700 kg·m/s

P_initial = P_final

41700 kg·m/s = (3000 kg + 1000 kg) * Vf

41700 kg·m/s = 4000 kg * Vf

Now Vf:

Vf = 41700 kg·m/s / 4000 kg

Vf ≈ 10.43 m/s

Therefore, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.
