Question

which physical indenty has unit-2​

Answer 1

Answer:

Given : ms⁻²

To find : physical identity has given unit

Solution:

ms⁻²

= m/s²

m - unit of length ( displacement / distance / length )

s = unit of time

Rate of change of distance / displacement is speed / velocity

m / s = velocity or Speed

Rate of change of velocity is acceleration

(m/s)/s = acceleration

=> m/s² = acceleration

=> ms⁻² = acceleration

acceleration has unit m/s²

Answer 2

Explanation:

Answer:

The value of the equation $\bold{\frac{2 x}{3}+1=\frac{7 x}{15}+3}$

Step-by-step explanation:

To solve the above equation we first solve both the parts separately,

Let us solve the first part,

$\frac{2 x}{3}+1=\frac{2 x+3}{3}$

After this, let us solve the second part

$\frac{7 x}{15}+3=\frac{7 x+45}{15}$

Equate both the parts together we get

$\frac{2 x+3}{3}=\frac{7 x+45}{15}$

Now on doing cross multiplication we get,

15(2x+3)=3(7x+45)

30x+45=21x+135

On solving this we get,

9x=90

x=10

Therefore, the value of x after solving the equation $\bold{\frac{2 x}{3}+1=\frac{7 x}{15}+3 \text { is } 10}$
