Answer:
It's Helium.
Explanation:
The superficial layers of the star compress the core as an effect of its own gravity. Therefore, atoms will be closer to each other in the core, allowing them to be combined.
A nuclear reaction occurs when light elements combine into heavier elements (that is known as nucleosynthesis). Different ways in which that can happen exist, but the most common in the Sun, according to its mass, is the Proton-Proton chain reaction. In that fusion reaction two atoms of Hydrogen are combined to form Helium.
Remember that a Helium atom is composed of two Protons and two Neutrons.
The Proton-Proton chain works in the following way:
+ = 
+ 
+ 
Two Protons combine each other () and one Deuterium () is gotten, and one Neutrino (), and one Positron () are emitted from them.
+ = 
+ 
A deuterium and Proton combine each other and a Helium three nucleus() is gotten, and a gamma ray () is emitted.
+ = 
+ +
Two Helium three nucleus combine and a Helium atom () is gotten, and two Protons are emitted.
So, when hydrogen atoms fuse together helium is created.
Answer:
Explanation:
As the 2 force directions are perpendicular (North vs West), we can calculate the magnitude of the net force using the following equation
Assuming negligible friction, from here we can calculate the acceleration in accordance to Newton's 2nd law of motion
This is the answer :)))))
Answer:
a. The moment of the 4 N force is 16 N·m clockwise
b. The moment of the 6 N force is 12 N·m anticlockwise
Explanation:
In the figure, we have;
The distance from the point 'O', to the 6 N force = 2 m
The position of the 6 N force relative to the point 'O' = To the left of 'O'
The distance from the point 'O', to the 4 N force = 4 m
The position of the 4 N force relative to the point 'O' = To the right of 'O'
a. The moment of a force about a point, M = The force, F × The perpendicular distance of the force from the point
a. The moment of the 4 N force = 4 N × 4 m = 16 N·m clockwise
b. The moment of the 6 N force = 6 N × 2 m = 12 N·m anticlockwise.
Answer: 90.1 s
Explanation:
Use equation for power:
P=F*V
Use eqation for force:
F=ma
F---force
V---velocity
Vr=om/s
V=30m/s
m=1000kg
P=10000W
---------------------------
P=FV
F=P/V
F=10000W/30m/s
F=333.33N
Use equation for force to find accelartaion.
F=ma
a=F/m
a=333.33N/1000kg
a=0.333 m/s²
Use equation for accelaration to find out time:
a=(V-Vs)/t
t=(V-Vs)/a
t=(30m/s)/(0.333m/s²)
t=90.09 s≈90.1 s
