Answer:

50N

Explanation:

Force (N) = mass (kg) × acceleration (m/s²)

0.25kg times 200m/s² = 50N

The _____ deflects these winds to the right in the northern hemisphere and to the Southern Hemisphere
almond37 [142]

Answer:

Coriolis Effect

Explanation:

The Coriolis effect is responsible for the deflection of winds to the right in the Northern hemisphere and to the right in the Southern hemisphere. It is an effect that occurs because of the rotation of the earth around its axis.

The implication of this is that in areas of low pressure in the Northern hemisphere, winds tend to blow in anticlockwise direction, and in areas of high pressure, it blows in a clockwise direction. The opposite of this happens in the Southern hemisphere.

An object is allowed to fall freely near the surface of an unknown planet. The object falls 72 meters from rest in 4.0 seconds.

<span>it fairly is going to attain a speed of 24 m/s in a 2d, yet between t = 0 and t = a million, it fairly is not any longer vacationing at that speed, yet at slower speeds. it fairly is 12 meters. ?D = [ ( a?T^2 + 2?Tv_i ) ] / 2 the place: ?D = displacement a = acceleration ?T = elapsed time v_i = preliminary speed ?D = [ ( 24m/s^2 • 1s • 1s + 2 • 1s • 0m/s ) ] / 2 ?D = 24 / 2 ?D = 12m</span>

The parking brake on a 1200kg automobile has broken, and the vehicle has reached a momentum of 7800kg.M/s. What is the velocity
AysviL [449]
Ok so the equation for momentum is:
v=p/m

So you would do:
7800/1200=6.5

So the answer is:
6.5 m/s

Hope this helps :)

A solar reflector is made using 31 identical triangular-shaped mirrors, each having sides . What is the total surface area of th
Stels [109]

Complete Question

Question 18 (3 points) Solve the problem. (3 points) A solar reflector is made using 31 identical triangular-shaped mirrors, each having sides 2.4m, 2. 3m, 1.5 m. What is the total surface area of the reflector?

A) 33 m2  

B) 86 m2

C) 52 m2

D)  34 m2

Answer:

The value is  Area  =2.78 \   m^2

Explanation:

From the question we are told that

   The  sides are  a =  2.4 m

                             b  =  2.3 m

                             c  =  1.5 m

Generally the semi perimeter is mathematically represented as

           s = \frac { a + b  + c  }{2 }

=>       s = \frac { 2.4  + 2.3  + 1.5   }{2 }

=>       s =3.1  \  m

Generally the using Heron's  formula we have that the  surface are a is  mathematically represented as

            Area  =  \sqrt{S (S -  a) (S - b )(S - c ) }

=>         Area  =  \sqrt{3.1  (3.1  -   2.4) (3.1  -  2.3 )(3.1  -  1.5 ) }

=>        Area  =2.78 \   m^2

Diagram shows the velocity time graph for a particle moving in 16 seconds.
Leya [2.2K]

Answer:

The detailed calculations are shown below;

Explanation:

a)The maximum acceleration of the particle:

  It is seen that the maximum change in velocity is at the time between 8s to 10s.

              Maximum acceleration: \frac{V}{t}

                                                    = \frac{20}{2}

                                                    = 10 m/s^{2}

b) The deceleration of the particle

          The velocity of particle is decreased after 10s so,

                     deceleration = - \frac{40}{6}

                                           = - 6.67 m/s^{2}

c)The total distance traveled by the particle = Area under the curve

                               = \frac{1}{2}* 4*20 + 4*20 +  \frac{1}{2}* 2*20+ 2*20+ \frac{1}{2}* 40*16

                                                       = 290 m

d)The average velocity of the particle = \frac{Area under the curve}{Total time}

                                                               = \frac{290}{16}

                                                               = 18.12 m/s
