If something weighs 2891N on earth, what’s it’s mass?

joja [24]

Answer:

289.1kg

Explanation:

because W=M*G, and M=W/G, so 2891N/10m/s²=289.1kg

A dad pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 18 rpm,

puteri [66]

Answer:

F = 176.175 N

Explanation:

given,

radius of merry - go - round = 2.7 m

mass of the disk = 800 kg

speed of the merry- go-round = 18 rpm

= 18 $\dfrac{2\pi }{60}$

= 1.88 rad/s

time = 13 s

mass of two children = 25 kg

ω = ω₀ + α t

1.88 = 0 + α(13)

α = 0.145 rad/s²

we know

τ = I α

so,

$I = \dfrac{1}{2}MR^2+ 2 MR^2$

$I = \dfrac{1}{2}\times 800 \times 2.7^2+ 2\times 25\times 2.7^2$

$I = 3280.5 kg.m^2$

τ = I α

τ = 3280.5 x 0.145

τ = 475.67 N m

τ = F x r

475.67 = F x 2.7

F = 176.175 N

an eagle has a mass of 8 kg and is flying 85 m above the ground with a speed of 20 m/s. what is the total mechanical energy of t

vivado [14]

Total Mechanical Energy = KE + PE

KE = (1/2)mv²

= (1/2)*8*20² = 1600 J

PE = mgh g ≈ 10 m/s²

= 8 * 10 * 85 = 6800J

Total Mechanical = 1600 + 6800 = 8400 J.

Where are you most likely to find a trench?

telo118 [61]

You are most likely to find a trench at a divergent boundary between two plates.

*additional note

You don't have to but if you want to I recommend downloading this:

https://phet.colorado.edu/en/simulation/legacy/plate-tectonics

I'm currently in seventh grade and the assignments we are given in science is focused on earth and its layers. (because of schools closing ya know, online assignments and stuff, our teacher gave this helpful simulation sort of game)

Hope that helps! (it's basically a simulation of how plates form the way they do)
