Answer:
a.) The main scale reading is 10.2cm
b.) Division 7 = 0.07
c.) 10.27 cm
d.) 10.31 cm
e.) 10.24 cm
Explanation:
The figure depicts a vernier caliper readings
a.) The main scale reading is 10.2 cm
The reading before the vernier scale
b.) Division 7 = 0.07
the point where the main scale and vernier scale meet
c.) The observed readings is
10.2 + 0.07 = 10.27 cm
d.) If the instrument has a positive zero error of 4 division
correct reading = 10.27 + 0.04 = 10.31cm
e.) If the instrument has a negative zero error of 3 division
correct reading = 10.27 - 0.03 = 10.24cm
The answer would be E, 1800. Why? bc if you're going 30 meters per second and trying to figure out how far you would go in a minute, you would multiply 30 x 60 bc there's 60 seconds in a minute. Giving you 1800 meters. hope this helped, have an amazing day :)<span />
A committee that is temporarily signed is called a Select Committee
Answer:
5.5 N at 50.8° north of west.
Explanation:
To find the resultant of these forces, we have to resolve each force along the x- and y-direction, then find the components of the resultant force, and then calculate the resultant force.
The three forces are:
(east)
(west)
(at 60° north of west)
Taking east as positive x-direction and north as positive y-direction, the components of the forces along the 2 directions are:
Threfore, the components of the resultant force are:
Therefore, the magnitude of the resultant force is
And the direction is:
And since the x-component is negative, it means that this angle is measured as north of west.
