How much time will it take a car travelling at 88 km/hr (55mi/hr)to travel 500km?

1 answer:

7 0

The time it will take for a car travelling 88 km/hr (55mi/hr) to travel 500km would be 3.5 hours.

How? Add 88 + 58.

That'll equal 143, then divide 500 ÷ 143 = 3.5

So, 3.5 is the time that the car will take travelling 88 km/hr trying to reach the destination of 500km.

3. The doctor notices that Janet has long fingernails, and comments that fingernails grow at a rate (or

Viktor [21]

Answer:

7.93 × 10⁻¹³ km/s

Explanation:

Step 1: Given data

Rate of growth of the fingernails (r): 2.50 cm/year

Step 2: Convert "r" from cm/year to km/year

We will use the following conversion factors.

1 m = 100 cm

1 km = 1000 m

$\frac{2.50cm}{year} \times \frac{1m}{100cm} \times \frac{1km}{1000m} = 2.50 \times 10^{-5} km/year$

Step 3: Convert "r" from km/year to km/s

We will use the following conversion factors.

1 year = 365 day

1 day = 24 h

1 h = 60 min

1 min = 60 s

$\frac{2.50 \times 10^{-5} km}{year} \times \frac{1year}{365day} \times \frac{1day}{24h} \times \frac{1h}{60min} \times \frac{1min}{60s} = 7.93 \times 10^{-13} km/s$

2.50 cm/year is equal to 7.93 × 10⁻¹³ kilometers/second.

How does the strength of a liquid’s intermolecular forces affect its viscosity

igor_vitrenko [27]

Answer:

Viscosity increases with stronger intermolecular forces

Step-by-step explanation:

<em>Viscosity</em> is the resistance of a liquid to flow.

A liquid can flow easily only if the molecules can move past each other with little resistance.

If there are strong intermolecular attractive forces among molecules, it is more difficult for them to move past each other.

For example, the molecules in molasses have strong attractive forces, so it is quite viscous.

Using the periodic table, answer the following question..How many atoms of neon are in 0.378g of neon (a) 6.02 x 10²³ atoms (b)

zmey [24]

Answer:

B 1.87×10^-²

Explanation:

20.1797 g Neon = 1 mol

0.378 g Neon = y

(Cross multiply)

20.1797y= 0.378 x 1

(Make y the subject of the formula)

y = 0.878/ 20.1787

y = 0.0187317

y = 0.0187 approx

y = 1.87 x 10^-²
