1.How many significant digits are in 101,407,063?
Answer:
There are 9 significant digits in 101,407,063.
Explanation:
Significant figures are the digits of a number that are meaningful in terms of accuracy. The include any non-zero digit, zeros between non-zero digits, and trailing zeros only when there is a decimal point.
1. A body has a velocity of 72 km/hr. Find its value in m/s.
72 Km/hr
= 72000 m/ 60×60 s
= 72000 m/ 3600 s
= 20 m/s
Answer is 20 m/s.

a washing machine of 46 ohm draws a current of 5A. Determine the power rating of the washing machine
Explanation:
P = V .I
from ohms law
V = I.R
P = I^2 .R
= 25 × 46 =1150 watt

One equation that describes motion of an object is
x = vt + xo, where x is the position of the object, v is
its speed, t is time, and xo is the initial position. Show
that the dimensions in the equation are consistent.
We have that the resultant equation is L=L we can say that the dimensions in the equation are consistent
From the Question we are given equation
[tex]x = vt + xo[/tex]
Generally
x = distance in meters(m)
v =velocity in m/s
t=time in secs
x_0=distance in meters(m)
Therefore
The Dimension of equation is
[tex]L=LT^{-1}*T+L\\\\L=L[/tex]
Hence, Given that the resultant equation is L=L we can say that the dimensions in the equation are consistent

The meter will read 0 ohms
The meter will short circuit and trip a protective circuit
The meter will read infinite ohms (as high as its scale goes)
The meter will show the equivalent voltage of the meter's internal battery
If the meter's battery is good and the meter is working OK, it should read zero ohms.
Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.
A bus traveling at 30 m/s accelerates at a constant rate of 2.4 m/s2 over a distance of 60 m.
What is its speed after accelerating?
Answer:
Speed is 34.5 m/s
Explanation:
From the third equation of motion:
[tex]{ \boxed{ \sf{v {}^{2} = {u}^{2} + 2as}}}[/tex]
v is final velocity, u is initial velocity, a is acceleration, s is displacement.
substitute:
[tex] {v}^{2} = {30}^{2} + (2 \times 2.4 \times 60) \\ {v}^{2} = 900 + 288 \\ {v} {}^{2} = 1188 \\ {v} = \sqrt{1188} \\ v = 34.5 \: m {s}^{ - 1} [/tex]

HELP ME!!! Explain why an object moves if the action-reaction forces are equal.
Answer:
explanation is below
Explanation:
Equal and opposing forces acting on the same object are referred to as balanced forces. That is why they cancel each other out. Action-reaction forces do not cancel out because they are equal and opposite forces acting on different objects. In fact, they frequently cause movement.
Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.
