Answer:

4.47

Explanation:

Given data

vector 1 = 2m/s

vector 2= 4 m/s

The expression for the magnitude of two vectors is

|a| = √v1^2+ v2^2

substitute

|a| = √2^2+ 4^2

|a| = √4+ 16

|a| = √20

|a| = 4.47

Hence the magnitude of the two vectors is 4.47

sweet-ann [11.9K]

Answer:

Centripetal acceleration will be equal to 10.66m/sec^2

Explanation:

We have given time taken to cover 180° is 0.5 sec

So time taken by 360° is equal to = 2×0.5 = 1 sec

Radius of the circle r = 0.520 m

So distance d=2\pi r=2\times3.14\times 0.520=3.2656m

So velocity v=\frac{distance}{time}=\frac{.2656}{1}=3.2656m/sec

We have to find the centripetal acceleration

Centripetal acceleration will be equal to a_c=\frac{v^2}{r}=\frac{3.2656^2}{1}=10.66m/sec^2

So centripetal acceleration will be equal to 10.66m/sec^2

Answer:

mass= 60kg

velocity= 10m/s

momentum = mass × velocity

p=m×v

p= 60×10

p= 600kgm/s

By applying a force of one Newton, one can hold a body of mass _​
SVEN [57.7K]

Answer:

By applying a force of one Newton, one can hold a body of mass of 102 gram.

Explanation:

  • Force is the pull or push of an object. It can be mathematically measured as, F= m* g.

                       where, F= force in newton

                                  m= mass in kg

                                  g= acceleration due to gravity (meter/second^{2} )

  • For 1 newton force,

                                   F= m* 9.8

                            or,   m= \frac{1}{9.8}= 0.102 kg

                            or,   m= 102 gram.

  • Hence, 102 gram mass can be hold by one Newton force.
