Answer:
distance travelled 7 metres and
displacement 3 metres
Explanation:
Distance travelled is the total diatance travelled by you which is 2m + 5m = 7m
Displacement is the shortest distance between two points start and stop which is 3m.
Answer:
The astronaut's mass is 16 kg.
Explanation:
Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
Therefore, if an astronaut has a mass of 16 Kg on Earth, his mass on the moon and on the space station would remain the same, as his original mass of 16 Kg because mass is indestructible.
Answer:
100 N
Explanation:
Given that,
Two forces whose resultant is 100newton are perpendicular to each other.
If one of them makes an angle of 60newton with the resultant.
![F_1=100\times \sin60=86.60\ N](https://tex.z-dn.net/?f=F_1%3D100%5Ctimes%20%5Csin60%3D86.60%5C%20N)
and
![F_2=100\times \cos60=50\ N](https://tex.z-dn.net/?f=F_2%3D100%5Ctimes%20%5Ccos60%3D50%5C%20N)
The magnitude of force,
![F=\sqrt{F_1^2+F_2^2} \\\\F=\sqrt{86.6^2+50^2} \\\\F=99.99\ N](https://tex.z-dn.net/?f=F%3D%5Csqrt%7BF_1%5E2%2BF_2%5E2%7D%20%5C%5C%5C%5CF%3D%5Csqrt%7B86.6%5E2%2B50%5E2%7D%20%5C%5C%5C%5CF%3D99.99%5C%20N)
or
F = 100 N
So, the magnitude of force is 100 N.
