Answer:
Real and inverted
Explanation:
Magnification of a lens is defined as the ratio of the height of the image to the height of the object.
Where
h' is the height of image
h is the height of the object
It is also defined as the ratio of image distance to the object distance.
Here, m = -0.6
Negative sign shows the image is inverted. So, the formed image will be real and inverted.
The answer is <span>A. A warm and humid day with a wind moving in the same direction as the sound.
Sound waves travel through a medium such as solid, liquid, or gas. It travels faster when the molecules of its medium are closer together. This is the reason why it travels the slowest through dry air. When air is wet or humid, sound can travel faster because sound travels faster through water.
When sound waves pass through air, the most important factor that affects it is temperature. The higher the temperature, the faster the molecules vibrate. This allows sound waves to travel faster.</span>
Speed= (frequency) x (wavelength)
= (2 per second) x (5 cm) = <em><u>10 cm/sec .</u></em>
From the calculations, the force required is 0.437 N.
<h3>What is force?</h3>
The term force is defined a the product of mass and acceleration. The force is required to move the sling the required distance.
If mass = 0.019 kg and acceleration = 23 m/s2 then we know that F = ma
It then follows that the required force is;
F = 0.019 kg * 23 m/s2= 0.437 N
Missing parts
You plan to use a slingshot to launch a ball that has a mass of 0.019 kg. You want the ball to accelerate straight toward your target at 23 m/s2. How much force do you need to apply to the ball?
