Physics
1 answer:
bezimeni [28]3 years ago
4 0

Explanation:

Let x = distance of F_1 from the fulcrum and let's assume that the counterclockwise direction is positive. In order to attain equilibrium, the net torque \tau_{net} about the fulcrum is zero:

\tau_{net} = -F_1x + F_2d_2 = 0

-m_1gx + m_2gd_2 = 0

m_1x = m_2d_2

Solving for <em>x</em>,

x = \dfrac{m_2}{m_1}d_2

\:\:\:\:=\left(\dfrac{105.7\:\text{g}}{65.7\:\text{g}} \right)(13.8\:\text{cm}) = 22.2\:\text{cm}

What has been happening to the cosmic microwave background radiation since the Big Bang?​
kondor19780726 [428]

Answer:

Explanation:

Cosmologists refer to a "surface of last scattering" when the CMB photons last hit matter; after that, the universe was too big. So when we map the CMB, we are looking back in time to 380,000 years after the Big Bang, just after the universe was opaque to radiation. But the CMB was first found by accident.
