To avoid compromising your car's aerodynamic properties, you should avoid ________.A. running your air conditioning system B. ta

king turns at high speeds C. carrying large loads on the outside of the vehicle

Answer:

C) True   carrying large loads on the outside of the vehicle

Explanation:

The aerodynamic property of an object depends on its outer shape. In general, objects should be thin in the front and not completely flat in the back, to avoid the eddies that create a great Arrate, losing all the aerodynamics of the system.

With this we can review the final statements

A) False The air conditioner is used with the glasses raised, so the exterior shape of the car does not change and its aerodynamics remains unchanged.

B) Phallus. This does not change the outer shape, I get a small inclination,

C) True. External loads dramatically change the external shape of the vehicle significantly reducing its aerodynamic characteristics.

When you look at yourself in a convex mirror, you appear to be ¼ your actual size. If you are standing 1.0 m in front of the mir
Nookie1986 [14]

Answer:

The focal length is   f  =  -0.2 \  m

The radius of curvature is R = -0.4 \  m

Explanation:

From the question we are told that

       The magnification of the mirror is  m =  \frac{1}{2}

       The distance of the person from the mirror(the object distance ) is  u = - 1.0 \ m

        The negative sign shows that it is been placed in front of the mirror

         

Generally the magnification of the mirror is mathematically represented as

       m  =  \frac{v}{u}

=>   \frac{1}{4}  = \frac{v}{-u}

=>   v  =  \frac{- 1}{4}

Generally from the lens equation we have that

        \frac{1}{f}  = \frac{1}{u}  + \frac{1}{v}

=>     \frac{1}{f}  = \frac{1}{-1 }  + \frac{1}{-\frac{1}{4} }

=>     f  =  -0.2 \  m

Generally the radius of curvature is  mathematically represented as

         R = 2 *  f

=>      R = 2 *   - 0.2

=>      R = -0.4 \  m

a spring is hanging down from the ceiling, and an object of mass m is attached to the free end. the object is pulled down, there
Maurinko [17]

The dimension of K is M/ T^2

according to the question T=2π square root ofm/k here 2 pi is constant so  

T= root of m /k and root of k = root of m/ T now by squaring on both the sides we get the answer k= M/ T^2

complete question :

A spring is hanging down from the ceiling, and an object of mass m is attached to the free end. The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and down, and the time T required for one complete up-and-down oscillation is given by the equation T=√2πm/k, where k is known as the spring constant. What must be the dimension of k for this equation to be dimensionally correct?

Precautions taken when doing experiment on simple pendulum​
olchik [2.2K]

Answer:

1.)The bob of pendulum should be displaced with a small angle.

2) The amplitude of the oscillation of a simple pendulum should be small.

3) Fans should be switched off to reduce the air resistance.

4)The simple pendulum should be oscillate in a vertical plane

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!!
