Which has greater force fly hitting windshield of rapidly moving car or the force of windshield hitting fly? Explain

1 answer:

3 0

The force applied on the fly and the windshield are equal based on Newton's Law of Action and Reaction. the difference between them is that the fly's body does not have enough mechanical strength to withstand the force but the windshield does.

17. If ice has a density of 0.92g/cm?, what is the mass of a 30 cm block?<br> I

arsen [322]

Answer:

Mass = 27.6 grams

Explanation:

Given the following data;

Density of ice = 0.92g/cm³

Volume = 30cm³

To find mass of ice;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

$Density = \frac{mass}{volume}$

Making mass the subject of formula, we have;

$Mass = density * volume$

$Mass = 0.92 * 30$

Mass = 27.6 grams

Therefore, the mass of ice is 27.6 grams.

A jogger runs 6 km north ,5 km east then another 4km north her average speed 8 km how long will it take her to complete her run

LekaFEV [45]

The time taken to complete her run is 1.9 hr.

<u>Explanation:</u>

Speed is a scalar quantity and it is defined as the ratio of distance covered to the time taken to cover that distance. As distance is also a scalar quantity, so the directions given in the problem can be ignored. Thus, the distance covered by the jogger is the sum of kilometers given in problem.

Distance covered = 6+5+4 = 15 km

And the speed is given as 8 km/hr.

So the time taken will be ratio of distance to speed.

$\text { time }=\frac{\text {distance}}{\text {speed}}=\frac{15}{8}=1.9 \text { hour }$

So the jogger will take 1.9 hr to complete her run.

How could you reduce the force needed to do work with a lever?

Klio2033 [76]

Answer:

I think

it works by reducing the amount of force needed to move an object or left the load

it does this by increasing the distance. it make the work easier by spreading out the effort over a longer distance
