Answer
Mass of motorcycle is 205 kg .
Explanation:
Formula
w = mg
Where w is the weight of an object , m is the mass of an object and g is the acceleration of gravity .
As given
A motorcycle weighs 2009 newtons.
g = 9.8 N/kg for gravity.
w = 2009 N
Putting the values in the formula
2009 = m × 9.8
m = 205 kg
Therefore the mass of motorcycle is 205 kg .
PART A)
Equivalent resistance in parallel is given as
now we have
PART B)
since potential difference across all resistance will remain same as all are in parallel
so here we can use ohm's law
for 4 ohm resistance we have
PART C)
since potential difference across all resistance will remain same as all are in parallel
so here we can use ohm's law
for 8 ohm resistance we have
Answer:
Canyon is 50.176 meter deep.
Explanation:
The students is standing on the rim of the canyon and drops down a rock from the rim(cliff). We have to find what is the depth of the canyon i.e. how much below is the ground from the cliff.
Given data:
Time = t = 3.2 s
Initial velocity = = 0 m/s
Gravitational acceleration = g = 9.8 m/s²
Height = h = ?
According to second equation of motion
As initial velocity is zero, So the first term of right hand side of above equation equal to zero
h = (0.5)(9.8)(3.2)²
h = 50.176 m
This means, the rock traveled 50.176 meters to reach the bottom of the Canyon. So, the Canyon is 50.176 meter deep.
