Answer with Step-by -step explanation:
We are given that 
b.
 below the positive x-axis
 below the positive x-axis
Therefore, the angle made by vector A in counter clockwise direction when measure from positive x-axis=
x-component of vector A=
y-Component of vector A=
Magnitude of vector B=86 m
The vector B makes angle with positive x- axis=
x-component of vector B=
y-Component of vector B=
Vector A=
Vector B=
Vector C=A+B
Substitute the values


c.Direction=
The direction of the vector C=21.5 degree
 
        
             
        
        
        
Answer:
-.457 m/s^2 
Explanation:
Actual weight =   60 .3 (9.81) = 591.54 N
Accel of lift changes this to    60.3 ( 9.81 - L)     where L - accel of lift 
                                            60.3 ( 9.81 - L ) = 564 
                                                solve for L = .457 m/s^2  DOWNWARD
                                                         so L = - .457 m/s^2 
 
        
             
        
        
        
Answer:
201.76266192 m
Explanation:
Distance traveled in the horizontal direction = 153 m
In the vertical direction the distance traveled

Total distance from pythagoras theorem

The total distance the boat will travel to reach the opposite shore is 201.76266192 m
 
        
             
        
        
        
The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
<h3>What is heating and cooling?</h3>
Heating is the process by which the temperature of a place or substances or object is increased.
Cooling Is the process of lowering the temperature of a substance or object by using conditioners or by freezing .
Therefore, The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
