So we want to know what is the magnitude of the horizontal component of acceleration ah if we know that the overall acceleration a=12 m/s^2 and the angle of overall acceleration and the horizontal acceleration is α=50°. We know that ah=a*cosα. So now it isn't hard to get the horizontal component: ah=12*cos50=12*0.64=7.71 m/s^2. So the correct answer is ah=7.71 m/s^2.
According to meteoric material, the solar system was formed around <u>4.6 billion years</u> ago.
<h3>What substance makes up a meteorite?</h3>
- With just trace levels of sulphide and carbide minerals, they are primarily composed of iron-nickel metal.
- Many asteroids melted during the radioactive element decay in the early solar system, and the iron they carried, being dense, sank to the centre to create a metallic core.
<h3>What is the term for meteorite metal?</h3>
- Meteoric iron, also known as meteoritic iron, is a native metal and a protoplanetary-disk remnant from the early universe that is found in meteorites.
- It is mostly composed of the metals iron and nickel, primarily in the crystalline phases kamacite and taenite.

Answer:
Explanation:
Action and reaction force are an integral part of third law of Newton . They are equal and opposite force - couple which act on two opposite objects. That is why they can not make a body in equilibrium.
In the given case, a bat is hit by a ball , at the point of contact , two equal and opposite forces emerge simultaneously , one acting on the ball and the other acting on the bat. As per the problem , force on the bat is called action . So the other force , that is force acting on the ball is called reaction force.
Answer:
2100 m
2804 g
4 '2 mm squares'
20,000 photos
Explanation:
1.5 km = 1500 m
1500 m + 600 m = 2100 m
2.8 kg = 2800 g
2800 g + 4 g = 2804 g
8mm tube / 2 mm squares
4 can fit
1 Gb = 1000 mb
40 Gb = 40,000 mb
40,000 mb / 2 mb = 20,000 photos
