Answer:

Accuracy

Explanation:

Accuracy means making measurements that are close to the value precision means making measurement that are close in value to eachother but not necessarily close to the true value.

I hope this helps! If not sorry.

A salt shaker sits 0.102 m from
Ivahew [28]

The maximum speed is 0.55 m/s

Explanation:

For an object in uniform circular motion, the force of friction between the object and the ground provides the centripetal force required to keep the body in motion. Therefore we can write:

\mu_s mg = m\frac{v^2}{r}

where the term on the left is the frictional force and the term on the right is the centripetal force, and where

\mu_s is the coefficient of static friction

m is the mass of the body

g is the gravitational acceleration

v is the speed of the body

r is the radius of the circular path

In this problem, we have:

\mu_s = 0.307

r = 0.102 m

g=9.8 m/s^2

Substituting and re-arranging, we find the maximum speed v at which the salt shaker can rotate:

v=\sqrt{\mu gr}=\sqrt{(0.307)(9.8)(0.102)}=0.55 m/s

A charge of 4.5x10^-5 C is placed in an electric field with a strength of 2.0x10^4 N/C. What is the electric force acting on the
Alex

Answer:

0.9 N

Explanation:

The electric force acting on a charge is given by:

F=qE

where

q is the magnitude of the charge

E is the strength of the electric field

In this problem, we have

q=4.5\cdot 10^{-5}C is the charge

E=2.0\cdot 10^4 N/C is the strength of the electric field

Substituting into the equation, we find

F=(4.5\cdot 10^{-5}C)(2.0\cdot 10^4 N/C)=0.9 N

Each bat can produce different frequencies of ultrasound. Explain why this is useful if there are many bats hunting together.
Crazy boy [7]

Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.
