It is also tripled, there is a rule to everything, whatever you do to one thing, you do the exact thing to the other. Hope this solves it :)
Answer:
Explanation:
A car of mass 1000kg pushes 2000kg
The forward force is 4500N
Then, summation of the forward forces is ma
ΣF = Σ(ma) = m1a1 + m2a2
Since the body are moving together then, they will have the same acceleration(a)
ΣF = Σ(ma) = (m1+m2)a
Let m1=1000kg.
m2=2000kg
F=4500N
Then,
4500=(1000+2000)a
4500=3000a
Then,
a=4500/3000
a=1.5m/s²
Answer: f = - 0.50 m, negative (diverging) lens
Explanation: D-value (diopter ) means 1/f, unit is 1/m. Thus -2.0D
Means f = ( 1/ -2.0 ) m = -0.50 m
3 ways would be they are used for movement, form structure and carry out reactions, processes, and cells
Explanation:
The frequency of the engine is given by :
We have, the engine increases its performance from zero to 2700 rpms.
Frequency,
The time period of the engine is given by :
T = f/f
So,
Hence, the required frequency and the period is 45 cycles/second and 0.023 seconds respectively.
