A train approaching a crossing changes speed from 10 m/s to 25 m/s in 240 s. How can the train's acceleration be described?
Gemiola [76]

Answer:

\boxed{\text{The train is speeding up by 0.0625 m/s every second}}

Explanation:

Acceleration (a) is the change in velocity (Δv) divided by the change in time (Δt).

a = \frac{\Delta v}{\Delta t} = \frac{v_{2} - v_{1} }{t_{2} - t_{1}} \\\\a = \frac{25 - 10}{240 - 0}=\frac{15 }{240}=\text{0.0625 m/s}^{2}\\\\\ \boxed{\textbf{The train is speeding up by 0.0625 m/s every second}}\\

How much energy is required to raise the temperature of 3 kg of iron from 20°
Vinvika [58]

Answer:

Option C (6750 J) is the appropriate response.

Explanation:

The given values are:

Mass of iron,

m = 3 kg

Specific heat capacity,

c_A = 0.450

Temperature,

T = 25-20

  = 5^{\circ}C

Now,

⇒  Q=mc_A T

On substituting the values, we get

⇒      =3\times 0.450\times 5

⇒      =6.75

i.e,

⇒      =6750 \ J

What elements form between polar covalent?
Ket [755]

Answer:

Nonmetal + nonmetal

Explanation:

Since it's a covalent bond, the bond is formed between two nonmetals, just like a regular covalent bond. However, the 'polar' just means that there is an overall dipole moment.
