Answer:
0.15N
Step-by-step explanation:
Given data
Mass= 0.0056kg
distance= 4.85m
Velocity= 11.4m/s
The expression for the force is
F= mv^2/r
substitute
F= 0.0056* 11.4^2/4.85
F= 0.0056*129.96/4.85
F= 0.727776/4.85
F= 0.15N
Hence the force is 0.15N
Answer:

Step-by-step explanation:
The binomials are multiplied in the usual way, using FOIL or the distributive property:
(5 -2i)(3 -4i) = 15 -20i -6i +8i²
Since i² = -1, this becomes ...
= 15 -20i -6i -8 = 7 -26i
Answer:
x=1, y=-5
Step-by-step explanation:
Given equations are:

In order to solve the equation
Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them
So,
Eqn 1 becomes
15x+50y=-235
Eqn 2 becomes
15x-21y=120
Subtracting 2 from a
15x+50y - (15x-21y) = -235-120
15x+50y-15x + 21y = -355
71y = -355
y = -355/71
y =-5
Putting y= -5 in eqn 1
3x+10(-5) = -47
3x -50 = -47
3x = -47+50
3x = 3
x = 3/3
x = 1
Hence the solution is:
x=1, y=-5
Answer:
70 + 7x
Step-by-step explanation:
7(8+x+2)
Combine like terms in the parenthesis
7(8+2+x)
7(10+x)
Distribute
70 + 7x
Answer:
Step-by-step explanation:
5p + 9c = p
9c = p - 5p
9c = -4p
c = -4p/9
c=
