Answer:
Explanation:
As we know that
mass of the string is
length of the string is given as
now we can find the linear mass density of the string as
Now we know the frequency of the string wave as
now we have
B:supported Copernicus heliocentric theory
Answer:
a= 2 m/s^2
Explanation:
take to the right as positive
let Ftot be the total forces acting on the box , m be the mass of the box and a be the acceleration of the box.
Ftot = 10 - 2 = 8 N
and,
Ftot = ma
a = Ftot/m
= 8/4
= 2 m/s^2
therefore, the acceleration of the box is of magnitude of 2 m/s^2.
Answer:
want
Explanation:
because it is not actually needed for the existence of life at that particular time
The displacement of Curiosity is 2.334 m
The given parameter:
maximum speed of Curiosity, v = 0.14 km/hr
time of motion of Curiosity = 60 s
To find:
- the displacement of Curiosity
The displacement of Curiosity is calculated as follows;
- convert the speed in km/hr to m/s by dividing by 3.6 km/hr
- 0.14 km/hr = 0.0389 m/s
The displacement of Curiosity = speed x time
The displacement of Curiosity = 0.0389 m/s x 60 s
The displacement of Curiosity = 2.334 m
Thus, the displacement of Curiosity is 2.334 m
