option C.
Explanation:
The correct answer is option C.
Vernier Calipers is a precision instrument that is used to measure the internal or outer dimensions or the depth of the material.
Vernier Caliper consists of two jaws, the main scale, and the vernier scale.
Graduation is present on both the main scale and vernier.
To measure the width of any material it should be placed in between the jaws and reading is taken with the help of the main scale and vernier scale.
The thickness of the candle can be measured using vernier calipers precisely.
You didn't give us a photo of Figure 4-18, so we don't know anything about
the sports car. But here's how to answer the question on your own:
Acceleration = (change in speed) divided by (time for the change)
and
Change in speed = (end speed) minus (start speed)
So, the garbage truck's acceleration is ...
(100 km/hr - 0) / (10 sec)
= 10 km/hr per second .
Calculate the acceleration of the sports car the same way,
and then you can compare them.
Answer:
(L: Length, T: Time)
p: Dimension: L; unit: m
q: Dimension: L/T or (L)*(T)^-1; unit: m/s
r: Dimension: L/T^2 or (L)*(T)^-2; unit: m/s^2
Explanation:
since y is distance (Length), make all terms L distance.
p is same as y dimension ==> dimension: L; unit: m (meter)
qt dimension is L ==> q dimension :L/T; unit: m/s
rt^2 dimension is L ==> r dimension : L/T^2; unit: m/s^2
