They have similar distances from the sun therefore receive similar amounts of solar energy but Venus has no atmosphere to protect it so greater variation in temp.
Both are rock planets unlike those further away from the sun which, because of their distance receive less solor energy are cold, are ice planets
The Himalayan Mountains formed at a convergence plate boundary between the Eurasian plate and the Indian plate.
Answer:
The velocity of the cart at the bottom of the ramp is 1.81m/s, and the acceleration would be 3.30m/s^2.
Explanation:
Assuming the initial velocity to be zero, we can obtain the velocity at the bottom of the ramp using the kinematics equations:
![v=v_0+at\\\\v^2=v_0^2+2ad](https://tex.z-dn.net/?f=v%3Dv_0%2Bat%5C%5C%5C%5Cv%5E2%3Dv_0%5E2%2B2ad)
Dividing the second equation by the first one, we obtain:
![v=\frac{v_0^2+2ad}{v_0+at}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bv_0%5E2%2B2ad%7D%7Bv_0%2Bat%7D)
And, since
, then:
![v=\frac{2ad}{at}\\\\v=\frac{2d}{t}\\\\v=\frac{2(0.50m)}{0.55s}\\\\v=1.81m/s](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B2ad%7D%7Bat%7D%5C%5C%5C%5Cv%3D%5Cfrac%7B2d%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cfrac%7B2%280.50m%29%7D%7B0.55s%7D%5C%5C%5C%5Cv%3D1.81m%2Fs)
It means that the velocity at the bottom of the ramp is 1.81m/s.
We could use this data, plus any of the two initial equations, to determine the acceleration:
![v=v_0+at\\\\\implies a=\frac{v}{t}\\\\a=\frac{1.81m/s}{0.55s}\\\\a=3.30m/s^2](https://tex.z-dn.net/?f=v%3Dv_0%2Bat%5C%5C%5C%5C%5Cimplies%20a%3D%5Cfrac%7Bv%7D%7Bt%7D%5C%5C%5C%5Ca%3D%5Cfrac%7B1.81m%2Fs%7D%7B0.55s%7D%5C%5C%5C%5Ca%3D3.30m%2Fs%5E2)
So the acceleration is 3.30m/s^2.
<h3><u>Answer;</u></h3>
D) Standing wave
<h3><u>Explanation;</u></h3>
- Standing wave also called stationary wave is a wave which oscillates in time but whose peak amplitude profile does not move in space.
- A standing wave pattern is a vibrational pattern created within a medium when the vibrational frequency of the source causes reflected waves from one end of the medium to interfere with incident waves from the source.
- Examples of standing waves include the vibration of a violin string and electron orbitals in an atom.
Connection to Big Idea about energy: Gravity creates gravitational potential energy. Gravitational energy relies on the masses of two bodies and their distance.
Connection to Big Idea about the universe: Gravitational force is exerted by all objects with mass throughout the Universe. It is what keeps the Earth and the planets in orbit around the Sun, and our Solar System in orbit around the centre of the Milky Way. Gravity is one of the forces involved in the birth of stars, their evolution and finally their death.
Connection to Big Idea about Earth: The gravitational force is responsible for many physical properties of Earth and consequently it affects the existence and the properties of living creatures on it. For instance, the existence, the chemical composition and the structure of Earth’s atmosphere was determined by Earth’s gravitational force.
