Physics

# In classical physics the force F acting on a body is assumed to be the product of mass m and acceleration a.If m=2.31 kg and acceleration is $3.123 m/s^2$,then taking into account significant figures the force F should be reported as

7.21 N

##### SOLUTION
$F=m \times a$
$=2.31 \times 3.123=7.21413 N$
Rounding off two decimal places since one of the products has two decimal places only.
$F=7.21 N$

You're just one step away

Q1 Subjective Medium
In the United States, a doll house has the scale of $1:12$ of a real house (that is,each length of the doll house is $\dfrac{1}{12}$ that of the real house) and a miniature house (a doll house to fit within a doll house) has the scale of $1:44$ of a real house. Suppose a real house has a front length of $20\ m$, a depth of $12\ m$, a height of $6.0\ m$, and a standard sloped roof (vertical triangular faces on the ends) of height $3.0\ m$ In cubic meters, what are the volumes of the corresponding
miniature house?
