Explanation:

1) Driving 60 miles per hour around a curve

2) Going from 0 to 60 miles per hour in 10 seconds

3) Slamming on the brakes to come to a stop at a stop sign

4) Driving in a straight line at 60 miles per hour

1) The speed is constant here, but in circular motion you have an acceleration that is v^2/r, where v is the speed and r the radius

2) You are accelerating from 0 to 60

3) You are desaccelerating

4) constant speed , no acceleration

Integrated circuits are used in virtually all modern electronic

marissa [1.9K]

Answer:

True.

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.

This electrical network which is usually a closed loop comprises of a device that provides the energy (voltage) to drive electrons or electric current; the device is referred to as a source such as a generator or battery.

Similarly, an integrated circuit (IC) also referred to as microchip can be defined as a semiconductor-based electronic component that comprises of many other tiny electronic components such as capacitors, resistors, transistors, and inductors.

Generally, integrated circuits (ICs) are used in virtually all modern electronic devices to carry out specific tasks or functions such as amplification, timer, oscillation, computer memory, microprocessor, etc.

A 0.150-kg glider is moving to the right with a speed of 0.80 m/s on a frictionless, horizontal air track. The glider has a head

victus00 [196]

Answer:

The final speed of 0.150-kg glider after collision is 3.2 m/s to the left

The final speed of 0.300-kg glider after collision is 0.20 m/s to the left

Explanation:

Given;

mass of glider moving to the right, m₁ = 0.150-kg

mass of glider moving to the left, m₂ = 0.300-kg

initial speed of glider moving to the right, u₁ = 0.80 m/s

initial speed of glider moving to the left, u₂ = 2.20 m/s

Apply the principle of conservation of linear momentum;

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(0.15 x 0.8) + (0.3 x - 2.2) = 0.15v₁ + 0.3v₂

-0.54 = 0.15v₁ + 0.3v₂

0.15v₁ + 0.3v₂ = - 0.54 -----------equation (i)

Again, their relative velocity after collision is given as;

u₁ - u₂ = v₂ - v₁

0.8 - (-2.2) = v₂ - v₁

3 = v₂ - v₁

v₂ = v₁ + 3 ------------equation (ii)

Substitute v₂ in equation (i)

0.15v₁ + 0.3v₂ = - 0.54

0.15v₁ + 0.3(v₁ + 3 ) = - 0.54

0.15v₁ + 0.3v₁ + 0.9 = - 0.54

0.45v₁ = - 0.54 - 0.9

0.45v₁ = -1.44

v₁ = -1.44 /0.45

v₁ = - 3.2 m/s

Thus, the final speed of 0.150-kg glider after collision is 3.2 m/s to the left

From equation (ii), v₂ = v₁ + 3

v₂ = -3.2 + 3

v₂ = - 0.20 m/s

Therefore, the final speed of 0.300-kg glider after collision is 0.20 m/s to the left
