Blank 1) axe
blank 2) less
blank 3) more
Answer:
a) 6.25 m/s
b) f = 832 N
Explanation:
given data:
mass of child = 36 kg
length 2.94 m
tension = 416 N
For part (A), we need to add the forces in normal direction F(n),
where T is tension
m is mass, g = 9.81 m/s^2, and
a is acceleration is given as.
where v is speed
r is the radius.
v = 6.25m/s
Part B)
F = 2*(416)
F = 832 N
Answer:
Explanation:
Rate of a reaction is defined as the rate of change of concentration per unit time.
Thus for reaction:
The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.
or
Thus
<h3>
Answer:</h3>
7000 Joules
<h3>
Explanation:</h3>
We are given;
- The mass of an object = 100 kg
But, Force = mass × g (taking g as 10 N/kg)
Assuming we are given the distance moved by the object as 7 m
We can calculate the work done by the force
We need to know that;
Work done = Force × distance
Therefore;
Work done = 1000 N × 7 m
= 7000 Joules
Therefore, the work done by the force is 7000 Joules
