I think is True: Because...

when you throw a disc you can throw it in any direction, many people call it "Flying Saucer" I'll give you an example ... When you throw something, for example a paper, you want to throw it at your classmate. You already know what address you want to send it to, then I say it is: True ...

Sorry if it's wrong :(

Answer:

a) f₁ = 3.50 m , b) f₂ = 0.84 m

Explanation:

For this exercise we must use the constructor equation

1 / f = 1 / p + 1 / q

where f is the focal length, p is the distance to the object and q is the distance to the image

a) the distance where the image should be placed is q = 3.50 m and the object is located at infinity p = ∞

1 / f₁ = 1 /∞ + 1 / 3.50

f₁ = 3.50 m

b) in this case the image is at q = -0.600 m and the object p = 0.350 m

1 / f₂ = 1 / 0.350 -1 / 0.600

the negative sign, is because the image is in front of the object

1 / f₂ = 1,1905

f₂ = 1 / 1,1905

f₂ = 0.84 m

A Dodge Stealth is driving at 70 mph on a highway. It passes a BMW going the same direction. The BMW is moving 7 mph backward relative the Dodge. 63 mph is the velocity of the BMW

Answer: Option A

Explanation:

Given is the speed of the dodge stealth as 70 mph passing by the BMW moving with 7 mph relative to Dodge. Thereby, to calculate the velocity of BMW, relative velocity concept has to be employed.

As we know that the relative velocity tells us about relative velocity of mobile reference system as the difference or sum of the initial reference system.

Therefore,

velocity of the BMW = $v_{b}$
