Answer:
11,100 N
Explanation:
Draw the car on the incline. Label the weight and normal forces. Call the direction normal to the incline y, and the direction parallel to the incline x.
If it helps, rotate the incline so that the surface of the incline is flat.
Use trigonometry to determine the components of the weight force. The y component of the weight is:
Wᵧ = mg cos θ
Wᵧ = (1150 kg) (9.8 m/s²) (cos 8.70°)
Wᵧ = 11,100 N
Answer:
v = 8.8 m /s
Explanation:
For listener and source going away from each other the formula of Doppler effect is as follows
V is velocity of sound , v is velocity of listner and source of sound
f₀ is apparent frequency and f is real frequency
V = 343 , v = ? ,f = 210 , f₀ = 221
Put these value in the relation above
![[tex]\frac{210}{221} = \frac{343-v}{343+v}](https://tex.z-dn.net/?f=%5Btex%5D%5Cfrac%7B210%7D%7B221%7D%20%3D%20%5Cfrac%7B343-v%7D%7B343%2Bv%7D)

v = 8.8 m /s
Answer:
Reduce you're speed, and let the other vehicle pass you
Answer:
Save the file and try to put stuff over the file. (kinda off like a picture)
the shadows are exactly the same length in the morning as they are in the evening.
is so obvious it’s that when the sun is low you get long shadows and when the sun is up in the sky like in the noon the shadow is shorter.
