Answer:

Acceleration(a)=3m/s^2

Time(t)=1min[1min=60s]

=1×60

=60s

Initial velocity(u)=0m/s

Velocity(v)=?

We know that,

Acceleration=v-u/t

Or,3m/s^2=v-0/60

Or,3×60=v-0

Or,v=180m/s

So,the velocity is 180m/s.

Hope,it will helpyouu!

-Dominant- [34]

Answer:

The dimensionality of B is length per cubic time.

Explanation:

Units for displacement and time are length $[L]$ and time $[T]$ , respectively. Then, formula can be tested for dimensional analysis as follows:

$[L] = B\cdot [T]^{3}$

Now, let is clear $B$ to determine its units:

$B = \frac{[L]}{[T]^{3}}$

The dimensionality of B is length per cubic time.

If the resultant of two velocity vectors of equal magnitude is also of the same magnitude, then which statement must be correct?

Tamiku [17]

The correct option is C) The angle between the vectors is 120°.

Why?

We can solve the problem and find the correct option using the Law of Cosine.

Let A and B, the given two sides and R the resultant (sum),

Then,

$R=A=B$

So, using the law of cosines, we have:

$R^{2}=A^{2}+B^{2}+2ABCos(\alpha)\\ \\A^{2}=A^{2}+A^{2}+2*A*A*Cos(\alpha)\\\\0=A^{2}+2*A^{2}*Cos(\alpha)\\\\Cos(\alpha)=-\frac{A^{2}}{2*A^{2}}=-\frac{1}{2}\\\\\alpha =Cos(-\frac{1}{2})^{-1}=120\°$

Hence, we have that the angle between the vectors is 120°. The correct option is C) The angle between the vectors is 120°
