Answer:
C
Explanation:
Graph C represents a linear function. As the height increases by 1 meter, the gravitational energy increases by 10 joules respectively.
Answer:
Explanation:
a ) When the box starts to slip
static friction = mg sinα
mg cosα x μ = mg sinα ( μ is coefficient of static friction )
Tanα = μ = .35
α = 19.2°
b ) Once box starts moving , kinetic friction will start applying on it
kinetic friction = mg cos19.2 x .25
= 2.31m
net force downward = mgsin19.2 - mgcos19.2 x .25
= m ( 3.22 - 2.31 )
= .91 m
acceleration downward ( a ) = .91 m / s²
c )
v² = u² + 2 a s
= 0 + 2 x .91 x 5
= 9.1
v = 3 m / s
The answer is A. With modern technology we have found that climate is much more than just the average temperature

Answer:
Option 3
Explanation:
O Option C is NEGATIVELY CHARGED, meaning it has GAINED ELECTRONS resulting in a GREATER number of ELECTRONS than PROTONS.
