A car travelling at 32 m/s decelerates at a rate of 6 m/s ^ 2 over 4 secondsWhat is the final velocity the car
Pachacha [2.7K]

Answer:

v=8m/s

Explanation

The initial velocity, u, of the car=32m/s

Since the car has decelerated, we negate the acceleration

This implies that,

a=-6m{s}^{ -2}

Time,t=4s

Let v be the final velocity,

using the relation,

a =  \frac{v - u}{t}

We obtain the below by substitution

- 6= \frac{v - 32}{4}

By cross multiplying we obtain,

- 6 \times 4 = v - 32

- 24=v-32

- 24+32=v

v=8m/s

Consider the addition of an electron to the following atoms from the third period. Rank the atoms in order from the most negativ
sergeinik [125]

The question is incomplete, the atoms in the third period referred to in the question are shown in the image attached.

Answer:

Cl>Si>Ar

Explanation:

Electron affinity refers to the energy released when an atom accepts electron (s) to form a negative ion. It is a periodic property that shows similar trends as electro negativity.

Considering the atoms in period three given in the question; chlorine will have the most negative value of electron affinity. This owes to the fact that halogens accept electrons easily to form negative ions. Silicon in group 14 shows much less negative value of electron affinity while argon, a noble gas, does not accept electrons at all and has an electron affinity of zero KJMol-1 by standard.

If a person whirls an object horizontally in a counter clockwise direction and the string breaks at point P as shown, what path
Nata [24]

when an object is revolving in circular path then its velocity is always along the tangent of the circular path

so while moving in circular path if the string is break then due to law of inertia the object will always move in the direction of initial motion

As we know that as per law of inertia if an object will not change its state of motion or state of rest until some external force will act on it.

So here also the object will move along its tangential direction once the string will break

so here the correct path will be

Option B
