PHYSICS

*not sure about the answer but here we go*

Mass = 425 kg

distance = 614.4 m

acceleration = 1.8 m/s²

Answer :

Count Force first.

$f \: = m \: \times a$

F = 425 × 1,8

F = 765 N ✅

Now let's count Work.

$w \: = \: f \: \times s$

W = 765 × 614.4

W = 470016 J ✅

Answer:

stars share a gravitational force with the galaxy while nearby galaxies do not share a gravitational field.

Explanation:

stars will not collide because they are bound by a gravitational orbit around the galaxy

What if when I find my product, I get the same compound as I did in my reactant? For example, FeCl3 + HCl ->FeCl3 + HCl. Then something is wrong. In this case, FeCl3 and HCl usually don't react. In very concentrated solutions of HCl, the FeCl4^- or FeCl6^-3 ion can form. In... There you go my friend

In a track and field event, a hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutio

lubasha [3.4K]

Answer:

5.69755 rad/s²

Explanation:

r = Radius = 1.3 m

v = Velocity of the hammer = 22 m/s

n = Number of revolutions = 4

Angular displacement

$\theta=n\times 2\pi\\\Rightarrow \theta=4\times 2\pi\\\Rightarrow \theta=8\pi$

$\omega_i$ = Initial angular speed = 0

Final angular speed

$\omega_f=\frac{v}{r}\\\Rightarrow \omega_f=\frac{22}{1.3}\\\Rightarrow \omega_f=16.92307\ rad/s$

Angular acceleration

$\alpha=\frac{\omega_f^2-\omega_i^2}{2\theta}\\\Rightarrow \alpha=\frac{16.92307^2-0^2}{2\times 8\pi}\\\Rightarrow \alpha=5.69755\ rad/s^2$

Angular acceleration is given by 5.69755 rad/s²

You should move this to Biology. Sorry I can't give you an answer though. Its been years since I have taken Biology.
If I had to guess though I would think the answer would be B. Take that with a grain of salt though.
