Answer:

Explanation:
Given
Points: (1,-1) and (-5,3)
Required
Determine the slope
The slope of a line is represented by m and is calculated as thus;

Where


Substitute these values in the given formula



Simplify fraction

Hence, the slope of the line is 
Answer:
(a) 
(b) 
Explanation:
Given:
- Limiting tension of snapping of the rope, T= 387 N
- Weight of the object to be lifted,

- ∴mass,

- height of letting down the weight, h = 6.1 m
(a)
Now,
The force to be compensated for being on the verge of snapping:
(T-w) = 62 N
Therefore, we need to produce and acceleration equivalent to the above force.
∵



(b)
From the equation of motion ,we have:
....................(2)
where:
u= initial velocity= 0 (here, starting from rest)
v= final velocity = ?

s= displacement =h =6.1 m
Now, putting the values in eq. (2)

is the velocity with which the body will hit the ground in the given conditions.
Explanation:
a)
Sum of moments = 0 (Equilibrium)
T . cos (Q)*L = m*g*L/2



b) If the String is shorter the Q increases; hence, Cos Q decreases which in turn increases Tension in the string due to inverse relationship!
c)

The appropriate response is false. Cathode-beam ray does not deliver pictures on the guideline of instigated emf. The cathode-ray is a high-vacuum tube in which cathode beams deliver an iridescent picture on a fluorescent screen, utilized mostly in TVs and workstations.
The answers are 3.3kWh, 1.2kWh, and 120kWh.
Multiply the amount of kW used per hour by the amount of time it was powered and you receive your answer.
