A car travels at a constant speed around a circular trackwhose
Mashutka [201]

Answer:

a = 0.77 m/s^2

Explanation:

The centripetal acceleration is given as

a = \frac{v^2}{R}

The velocity of the car can be calculated using the circumference of the track and the period of the car.

2\pi R = v T\\2\pi 2.6 = v 360\\v = 0.045 ~km/s = 45~m/s

So, the acceleration is

a = \frac{45^2}{2.6\times 10^3} = 0.77~m/s^2

Several days after snowfall , the roofs of some homes on your street have almost no snow on them, while the roofs on other homes
Alina [70]

Explanation:

This due to thermal insulation of some of the roof.

An insulator is body is a poor conductor of heat and will require high thermal energy to cause temperature changes.

  • A house with a roof that is thermally insulated will have poor heat conduction.
  • Since little heat is conducted, there wont be enough thermal energy to melt the snow.
  • Thermal energy is directly related to heat.
  • A house that is not insulated will absorb a lot of heat.
  • This will cause the snow to melt very fast.

A particle of mass m= 2.5 kg has velocity of v = 2 i m/s, when it is at the origin (0,0). Determine the z- component of the angu
melomori [17]

Answer:

please read the answer below

Explanation:

The angular momentum is given by

|\vec{L}|=|\vec{r}\ X \ \vec{p}|=m(rvsin\theta)

By taking into account the angles between the vectors r and v in each case we obtain:

a)

v=(2,0)

r=(0,1)

angle = 90°

L=(2.5kg)(1)(2\frac{m}{s})sin90\°=5.0kg\frac{m}{s}

b)

r=(0,-1)

angle = 90°

L=(2.5kg)(1)(2\frac{m}{s})sin90\°=5.0kg\frac{m}{s}

c)

r=(1,0)

angle = 0°

r and v are parallel

L = 0kgm/s

d)

r=(-1,0)

angle = 180°

r and v are parallel

L = 0kgm/s

e)

r=(1,1)

angle = 45°

L = (2.5kg)(2\frac{m}{s})(\sqrt{2})sin45\°=5kg\frac{m}{s}

f)

r=(-1,1)

angle = 45°

the same as e):

L = 5kgm/s

g)

r=(-1,-1)

angle = 135°

L=(2.5kg)(2\frac{m}{s})(\sqrt{2})sin135\°=5kg\frac{m}{s}

h)

r=(1,-1)

angle = 135°

the same as g):

L = 5kgm/s

hope this helps!!
