Answer:
The car travel 2.52 m
Explanation:
This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.
Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.
v = d / t
d = v t
d = 14 0.18
d = 2.52 m
The car travel 2.52m
Machines capable of manufacturing exactly the same component time after time,
with exactly the resistance you want, would be very expensive, and so would the
products they turn out. A resistor would cost a dollar instead of a few pennies.
The machine itself, and its output, work within tolerances.
The cheapest mass-produced resistors are guaranteed to be within 20% above
or below the resistance marked on them. And you know what ? For most bench-
work and prototyping, that's usually close enough.
I did the test and the anwser is d- the chromosome pairs collect in a line across the middle of the cell
Answer:
The correct solution is "64 RPM".
Explanation:
The given values are:
Mass,
M = 2.3 kg
Diameter,
D = 20 cm
i.e.,
= 0.2 m
Rotates at,
N = 110 rpm
Mass of block,
m = 460 g
i.e.,
= 0.46 kg
According to angular momentum's conservation,
⇒ 
then,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
Now,
⇒ 
then,
⇒ 
⇒ 
⇒ 
⇒ 
Answer:
The product of the mass and the volume is known as momentum.
According to the law of momentum, it is stated that the two or more bodies remain in a constant state unless an external force is applied in an isolated room.
Momentum depends on the following:-
Mass
Velocity
Momentum = MASS \ X \ VOLUMEMomentum=MASS X VOLUME
\begin{gathered}momentum = 3000kgm/s\\\\mass = 2000kg\\\\velocity =\frac{momentum}{mass}\\\\v= \frac{3000}{2000} \\\\v= 1.5m/s\end{gathered}
momentum=3000kgm/s
mass=2000kg
velocity=
mass
momentum
v=
2000
3000
v=1.5m/s
