How does the mass of a wheelchair influence the force needed to move it?

Answers

Answer:

When mass is greater, the force needed must be greater keeping the acceleration of the wheel chair constant

Explanation:

[tex]force = mass \times acceleration \\ f \: \alpha \: m[/tex]

force is directly proportional to the mass

The force needs greater keeping of the wheel chair

A car is moving at 80km/h accelerates to pass a truck. Five seconds later the car is moving at 100km/h. What is the Acceleration of the car? Please show the equation, Ty.

Answers

Answer/Explanation:

Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:

acceleration = v - v0 / t

acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s

acceleration = 1.67 x 10^-3 m / s^2

a = V2-V1 ÷ Δt
a = 27.78 m/s - 22.2 m/s ÷ 5 seconds
a = 1.116 m/s ²

*you needed to convert the km/h to m/s for proper evaluation, which is what i did*

Which spring has more potential energy stored?
a) 1.0 N/m constant spring stretched 0.2 m.

b) 2.0 N/m constant spring stretched 0.2 m.

c) 1.0 N/m constant spring stretched 0.3 m.

d) 2.0 N/m constant spring stretched 0.3 m.

Answers

Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.

Answer: c) 1.0 N/m constant spring stretched 0.3 m.

Which most likely has the greatest conductivity? a warm plastic rod a cool rubber tube a cool silver strip a warm copper wire

Answers

Answer:

Copper

Explanation:

Plastic and Rubber are both bad conductors of electricity so it cant be those

Copper is a good conducter of electricity since it warms up it allows electrons to move easily faster than silver.

A cool silver strip most likely has the greatest conductivity.

What is meant by conductivity ?

The ability of a material to transmit heat or an electric charge through it is measured by its conductivity.

Here,

A conductor is a substance that offers extremely little resistance to the transmission of thermal or electrical energy.

Metals, semiconductors, and insulators are the three main categories of materials. The least conductive materials are called insulators which include ceramic, wood, and plastic, while metals are the most conductive materials.

Of all metals, silver has the highest electrical conductivity. In actuality, silver is the benchmark metal against which all other metals are measured for conductivity.

On a scale of 0 to 100, silver scores a perfect 100, followed by copper at 97 and gold at 76.

Hence,

A cool silver strip most likely has the greatest conductivity.
