Answer:

t = 30 s

d = 1125 m

Explanation:

t = v/a = 75/2.5 = 30 s

d = v²/2a = 75²/(2(2.5)) = 1125 m

or

d = ½at² = ½(2.5)30² = 1125 m

What would the answer be​
wariber [46]

Answer:

D

Explanation:

The density has a formula of d = m / V.

The volumes are given as the same.

The density will be

d_lead = 113/ V

d_aluminum = 27/V

It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.

A: incorrect. If the volumes are the same, the density is not the same because the masses are different.

B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.

C: incorrect. The exact opposite is the answer.

D: Correct. This is the answer.

Please help! Find the time. 8 POINTS!!
Fantom [35]

Answer:

Time = 4.1 s

Explanation:

Momentum = mv = (12000)(4.25) = 51000 kg m/s

Momentum = Impulse (mv = ft) so

51000 = (9200)t

t = (51000)/(9200) = 5.54 seconds

Impulse of the current and the engine must equal so (ft = ft)

51000 = (12500)t

t = (51000)/(12500) = 4.08

But accounting for significant figures, time equals 4.1 seconds

Could someone please tell me what I'm doing wrong?
7nadin3 [17]

Answer:

M1 = 16.9 mA

M2 = 0 A

Explanation:

As the ratio of the two sets of series resistors is almost exactly identical, there is no voltage difference across M2 to cause current flow

269/(269 + 439) = 0.3799...

500/(500 + 815) = 0.38022

M2 = 0

M1 sees only the current flowing through the far left resistors in series

A = V/R = 12/(269 + 439) = 0.016949... ≈ 16.9 mA

Field lines become straight and perpendicular because every point of circular loop the concentric circles become larger and larger as we move away from the wire.
