Answer:
Step-by-step explanation:
we know that
The surface area of a cylinder is equal to
we have
----> the radius is half the diameter
assume
substitute
A : 10000 J
B: 625 J
C: 2500 J
Step-by-step explanation:
Step 1:
We know that ,
Kinetic Energy is given by ((1/2) × m × V²) J
where m = Mass of substance
V = Velocity
Step 2:
In first case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 20 ×20
= 10000 J
In second case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 5 ×5
= 625 J
In Third case, m= 50 kg, V=10 m/s
Kinetic energy = 0.5 × 50 × 10 ×10
= 2500 J
Answer:
or,3x-6=9x
or,3x-3x=6
or,x=-1
is this how u do it please let me know
Answer:
(1 + √2)/2
Step-by-step explanation:
Assuming the values are in degrees,
sin(45) = sin(π/4)=√2/2
cos(60) = cos(π/3)=1/2
thus
sin(45) + cos(60) = √2/2 + 1/2 = (1 +√2)/2
