To show that the expression given is dimensionally correct, we can do a dimensional analysis where we write the units of each term in the expression.

vf [=] vi + at 
m/s [=] m/s+ (m/s²) (s)
<span>m/s [=] m/s+ m/s
</span><span>m/s [=] m/s
</span>
Therefore, the expression is dimensionally correct.

Two objects are connected by a string that passes over a frictionless pulley as in the figure below, where m1 &lt; m2 and a1 and
Lady_Fox [76]

Answer:2

Explanation:

Given

m_2>m_1

and a_1 and a_2 are the acceleration of 1 and 2

Suppose  T is the Tension

then for block 2

m_2g-T=m_2a

m_2(g-a)=T---1

For block 1

T-m_1g=m_1a

T=m_1(g+a)----2

equate 1 and 2

m_2(g-a)=m_1(g+a)

a=\frac{m_2-m_1}{m_1+m_2}

where a=a_1=a_2

thus we can see that a is less than g

therefore a_2 < g

Whar determines the direction of ocean currents​
Arturiano [62]

Answer:

The direction in which they rotate is determined by the hemisphere in which they are located. The main overall global wind patterns, the rotation of the Earth, and the shape of ocean basins are the three major factors that decide surface currents.
