6 0

Answer:

48 kg

Explanation:

If you observe very closely, 55 would end up being closer to 60 than towards the middle. 48 lines up with the "disturbance of the force" more so than 55.

A. An object takes 5 s to reach the

Komok [63]

Answer:

g = 0.4 m/s²

Explanation:

Given the following data;

Height = 5 meters

Time = 5 seconds

To find the acceleration due to gravity (g) on the planet;

Mathematically, the maximum height of an object is given by the formula;

H = ½gt²

Where;

H is the height measured in meters.

g is the acceleration due to gravity.

t is time measured in seconds.

Substituting into the formula, we have;

5 = ½ * g * 5²

5 = 0.5 * g * 25

5 = 12.5 * g

g = 5/12.5

g = 0.4 m/s²

Compute the resistance in ohms of a silver block 10 cm long and 0.10 cm2 in cross-sectional area. ( = 1.63 x 10-6 ohm-cm)

Vedmedyk [2.9K]

The resistance of the silver block is given by
$R= \frac{\rho L}{A}$
where
$\rho=1.63 \cdot 10^{-6} \Omega \cdot cm$ is the silver resistivity
$L=10 cm$ is the length of the block
$A=0.10 cm^2$ is the cross-sectional area of the block

If we plug the data into the equation, we find the resistance of the silver block:
$R= \frac{(1.63 \cdot 10^{-6} \Omega \cdot cm)(10 cm)}{0.10 cm^2}=1.63 \cdot 10^{-4} \Omega$

A cheetah can run from 0 to 70 mph in 2.2 seconds. what is speed in m/s

sattari [20]

70 mph

= 70 * 1600 m/h

= <span>112000 m/h

-> 112000 m/h

= 112000 /3600 m/s

= 31.111... m/s

= <u>31 m/s (2s.f)</u></span>
