Find the number of hours by dividing the distance by mph. The number of hours will be to the left of the decimal point:

250 miles / 65 mph
= 3.846153846
= 3 hours

2) Find the number of minutes by multiplying what is remaining from step 1 by 60 minutes. The minutes will be to the left of the decimal point:

0.846153846 x 60
= 50.76923076
= 50 minutes

3) Find the number of seconds by multiplying what is remaining from step 2 by 60 seconds. The seconds will be to the left of the decimal point:

0.76923076 x 60
= 46.1538456
= 46 seconds

So 3 hours 50 mins and 46 seconds

A toy doll and a toy robot are standing on a frictionless surface facing each other. The doll has a mass of 0.2 kg, and the robo

Natali5045456 [20]

Answer:

Explanation:

According to newtons second law.

F = mass * acceleration

If the doll has a mass of 0.2 kg, and the robot has a mass of 0.5 kg, the resulting mass will be 0.7kg

Force applied = 1N

acceleration = Force/mass

Substitute the values and get acceleration

acceleration = 1/0.7

acceleration = 1.43m/s²

Hence the magnitude of the acceleration of the robot is 1.43m/s²

A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon

Furkat [3]

Answer:

Explanation:

According to Boyle's law:

$P\times V=constant$

Thus,

$P_{cylinder}\times V_{cylinder}=n\times P_{balloon}\times V_{balloon}$

Where, n is the number of the balloons

From the question, it is given that:

For balloon:

P = $1.2\times 10^5$ Pa

V = 0.040 m³

For cylinder:

P = $1.80\times 10^7$ Pa

V = 0.0031 m³

So,

$1.80\times 10^7\times 0.0031=n\times 1.2\times 10^5\times 0.040$

n = 11.625

<u>So, Maximum number of balloons = 11</u>
