Give an example of how you could make a measurement that is, at the same time, very precise and very inaccurate

Physics
1 answer:
LekaFEV [45]3 years ago
3 0

Answer:

Accuracy refers to how close a measurement is to the true or accepted value. ... Precision is independent of accuracy. That means it is possible to be very precise but not very accurate, and it is also possible to be accurate without being precise. The best quality scientific observations are both accurate and precise.

A 43-N crate is suspended from the left end of a plank. The plank weighs 21 N, but it is not uniform, so its center of gravity d
lesya [120]

Answer:

d_{2}=0.585m

Explanation:

The torque is the force by the distance so to determinate that both torque are the same magnitude so

T_{1}-T_{2}=0

T_{1}=T_{2}

F_{1}*d_{1}=F_{2}*d_{2}

43N*0.30m=21N*d_{2}

Solve to d2

d_{2}=\frac{41N*0.30m}{21N}

d_{2}=0.585m

An unbalanced force of 20N acts on a 4.0kg mass what is it's acceleration​
tankabanditka [31]

Hi there!

According to Newton's second law:

∑F = m · a, where:

∑F = net force (N = kgm/s²)

m = mass (kg)

a = acceleration (m/s²)

Rearrange to solve for acceleration:

F/m = a

20N / 4.0kg = 5 m/s²

The focal length for a spherical convex mirror is –20 cm. What is its radius of curvature?
Svetradugi [14.3K]

Answer:

40 cm

Explanation:

The focus of a spherical convex mirror is the point at which the rays of an object converge in the infinite, it is also the point at which an object must be placed so that its image is formed in the infinite. The distance from the focus to the origin is called the focal length and is called f. It is related to the radius of the mirror, R, according to:

f=-\frac{R}{2}

rewriting for R:

R=-2f=-2*-20cm=40 cm.
