Answer:
Magic school bus on ya left! so basically a star is born when like....atoms are like squeezed with enough pressure and kinda squished together, once tht happens the atoms start to fuse together
Explanation:
So the equation used in this problem is ΔX=V0*T+1/2AT^2 the X is the distance, v0 is initial velocity, T is time, and a is acceleration. So when we plug these values it we get: 108= 0•T+1/2•3•T^2,the 0•t disappears, and the 1/2•3 gets us 1.5, so we have 108=1.5T^2, then we divide 108 by 1.5 which gets us 72=t^2, and we then take the square root and get 8.49=T so the answer is 8.49 seconds.
Answer:
10N
Explanation:
The formula for calculating the resultant is expressed as;
R = √F1²+F2²
F1 and F2 are the forces
Given
F1 = 6.0N
F2 = 8.0N
R = √6²+8²
R = √36+64
R = √100
R = 10.0N
Hence the magnitude of the net force is 10N
