A car of weight 6,400 N has four wheels. Each wheel has an area of

Physics
1 answer:
Natasha2012 [34]3 years ago
6 0

Answer:

80N/cm^2

Explanation:

Given data

A car of weight 6,400N

Area= 80cm^2

The weight is distributed evenly on the 4 wheels

hence 6400/4

=1600 N

We know that

Pressure = force/Area

Pressure= 1600/80

Pressure= 20 N/cm^2

For the four wheels, the pressure is

=20*4

=80N/cm^2

The Kyoto Protocol, which limits emissions of greenhouse gases for developed nations, is an example of international Law

Explanation:

The Kyoto Protocol is named after a Japanese city in which it was executed in the year 1997 on 1st December.

The basic aim of the Kyoto Protocol is to reduce/Limit  the emission of greenhouse gases which contributed to  global warming

The Protocol was linked to the United Nations Framework Convention on Climate Change (UNFCCC)

The important factor that led to the failure of Kyoto's Protocol  are deficiencies in the structure of the agreement, such as the exemption of developing countries from reductions requirements, or the lack of an effective emissions trading scheme

23. What does a step-up transformer do?
nadya68 [22]

Answer: A transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. As a step-down unit, this transformer converts high-voltage, low-current power into low-voltage, high-current power.

An astronaut is being tested in a centrifuge. The centrifuge has a radius R and, in starting, rotates according to θ = tn, where
Igoryamba

Answer:

a) ω=n

b) V = R*n

c) a = 0

d) ar = R*n^2

Explanation:

Angular velocity is given by the derivative of θ:

ω = n

Linear Velocity will be:

V = ω*R = n*R

Tangential acceleration will be the derivative of the linear velocity. Since velovity is constant:

a = 0

Radial acceleration is given by:

ar = V^2/R = (R*n)^2/R=R*n^2
