The finished product or waste that forms as a result of a process is known as output.

The process of waste management is referred to as waste disposal, where a sizable proportion of this waste is composed by industrial and dangerous waste. Dangerous and non-dangerous industrial waste should also be very careful managed.

Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 50 km/h. After six hours,

Xelga [282]

A )
t 1 = 2 h, t 2 = 6 h
Δ t = t 2 - t 1 = 6 - 2 = 4 h
54 = 50 + a Δ t
54 = 50 + 4 a
4 a = 54 - 4
4 a = 4
a = 4 : 4
a = 1 km/h²
v o = 48 km/h
An equation that can be used to describe the velocity of the car at the different times is:
v = 48 + t
B ) The graph is in the attachment.

A rope of negligible mass passes over a uniform cylindrical pulley of 1.50kg massand 0.090m radius. The bearings of the pulley h

boyakko [2]

Answer:

Explanation:

mass of pulley, m3 = 1.5 kg

Radius of pulley, R = 0.09 m

mass of monkey, m2 = 4.5 kg

mass of banana bunch, m1 = 3 kg

Let a is teh acceleration ans T1 and T2 be the tension in the rope.

The moment of inertia of the pulley

I = 0.5 x m3 x R² = 0.5 x 1.5 x 0.09 x 0.09 = 0.006075 kgm²

According to Newton's second law

T1 - m1 g = m1 x a .... (1)

m2 g - T2 = m2 x a ..... (2)

(T2 - T1 ) x R = I x α

where, α is the angular acceleration

α = a / R

(T2 - T1)R = 0.5 x m3 x R² x a / R

T2 - T1 = 0.5 x m3 x a ..... (3)

from (1), (2) and (3)

$a = \frac{m_{2}-m_{1}}{m_{1}+m_{2}+\frac{m_{3}}{2}}\times g$

$a = \frac{4.5-3}{3+4.5+0.75}\times 9.8$

a = 1.78 m/s²

from equation (1)

T1 = m1 ( g + a) = 3 ( 9.8 + 1.78) = 34.77 N

from equation (2)

T2 = m2 (g - a) = 4.5 (9.8 - 1.78) = 36.13 N

(4%) Problem 9: A mass is connected to a spring and is allowed to move horizontally. The mass is at a position L when the spring

skad [1K]

Answer:

a) Acceleration is zero , c) Speed is cero

Explanation:

a) the equation that governs the simple harmonic motion is

x = A cos (wt +φφ)

Where A is the amplitude of the movement, w is the angular velocity and φ the initial phase determined by the initial condition

Body acceleration is

a = d²x / dt²

Let's look for the derivatives

dx / dt = - A w sin (wt + φ)

a = d²x / dt² = - A w² cos (wt + φ)

In the instant when it is not stretched x = 0

As the spring is released at maximum elongation, φ = 0

0 = A cos wt

Cos wt = 0 wt = π / 2

Acceleration is valid for this angle

a = -A w² cos π/2 = 0

Acceleration is zero

c) When the spring is compressed x = A

Speed is

v = dx / dt

v = - A w sin wt

We look for time

A = A cos wt

cos wt = 1 wt = 0, π

For this time the speedy vouchers

v = -A w sin 0 = 0

Speed is cero

In what stage do children see the world in an egocentric way?

zheka24 [161]

Answer: Preoperational stage (second stage).

Explanation: In the second stage of Child's development i.e., from the age of 2 years to 7 years approximately, which is called as Preoperational stage, a child develops a strong sense of Egocentrism. It is a situation where a child is unable to see thing from other peoples' eye and feels that everyone's reaction to something should be same as the child's. At this stage, a child is busy and completely trapped in his own dreamy world and is not ready to understand things properly.

Hence, the stage is Preoperational stage.
