Answer:
a=12 m/s²
Explanation:
Newton's second law of motion states that the acceleration of a body is directly proportional to the force applied and takes place in the direction of force.
This can be summarized as: F=ma, where m is the mass of the object on which force F acts. a is the acceleration due to the force applied.
12N= 1kg×a
a=12N/1kg
a=12m/s²
Gravity is the force of attraction between objects. Gravity is that force of attraction that will cause hydrogen gas in a nebula to clump together overtime. These hydrogen atoms will form a spinning cloud of gas within the nebula.
As collisions between the atoms become more frequent, the temperature within the cloud will rise.
As the cloud gets more massive the greater the force of gravity will be and so it will attract even more gas to the spinning cloud. When the temperature reaches fifteen million degrees Celsius, nuclear fission begins and a star is born.
Answer:
With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. ... With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.
Answer: To boost its acceleration because the Earth rotates Eastwards and to ensure that any crash will occur on an ocean and huge loss in life and properties will be averted.
Explanation: A space shuttle turns to the east as soon as possible,this is to ensure that the space shuttle acceleration is supported by Earth rotation which is also Eastwards.
Another reason for ensuring that the space shuttle turns Eastwards as soon as possible is to prevent a huge loss of life if there is any chance of crash by the space shuttle.When the space shuttle turns Eastwards it will ensure that any crashing will possibly be on the an ocean hence a huge loss of life an property in populated areas will be averted or reduced.
Answer: Chloroplast
Explanation: Chloroplasts work to convert the Sun's light energy into sugars that cells can use. It's like a solar panel that converts energy from sunlight into electric power.
