6. An excited dog runs full-speed toward his owner who has just returned home from

Physics
1 answer:
mixas84 [53]3 years ago
4 0

Answer:

v = 8.65 m/s

Explanation:

Given that,

Distance covered by the doge, d = 45 m

Time taken, t = 5.2 s

We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,

v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s

So, the average speed is 8.65 m/s.

Millikan measured the electron's charge by observing tiny charged oil drops in an electric field. Each drop had a charge imbalan
IceJOKER [234]

Answer:

4.8\cdot 10^{-19} C

Explanation:

For a drop in equilibrium, the weight is equal to the electric force (in magnitude):

W = F_e

where here we have

W=1.00\cdot 10^{-14}N is the weight of the drop

F_e is the magnitude of the electric force, which can be rewritten as

F_e = qE

where

q is the charge of the oil drop

E=2.08 \cdot 10^4 N/C is the magnitude of the electric field

Substituting into the equation and solving for q, we find the charge of the oil drop:

q=\frac{W}{F_e}=\frac{1.00\cdot 10^{-14}N}{2.08\cdot 10^4 N/C}=4.8\cdot 10^{-19} C

What is the cheetah's average speed for the first 3.11 s of its sprint? for the second 3.11 s of its sprint?
photoshop1234 [79]
<span>when you say a=4.02 i am going to acceleration in m/s^2. If the acceleration is 4.02 then you take the integral to find the speed. speed=4.02 t where t is time in seconds. [4.02(0)+4.02(3.11)]/2=6.2511 [4.02(3.11)+4.02(6.22)]/2=18.7533</span>

2 a A pile of 60 sheets of paper is 6 mm high. Calculate the average thickness of a sheet of the paper.
fiasKO [112]

The average thickness of a sheet of the paper is 0.1 mm.

The number of ice blocks that can be stored in the freezer is 80 blocks of ice.

<h3>Average thickness of a sheet of the paper</h3>

The average thickness of a sheet of the paper is calculated as follows;

average thickness = 6 mm/60 sheets = 0.1 mm /sheet

Thus, the average thickness of a sheet of the paper is 0.1 mm.

<h3>Volume of each block of ice</h3>

Volume = 10 cm x 10 cm x 4 cm

Volume = 400 cm³

<h3>Volume of the freezer</h3>

Volume = 40 cm x 40 cm x 20 cm = 32,000 cm³

<h3>Number of ice blocks that can be stored</h3>

n = 32,000 cm³/400 cm³

n = 80 blocks of ice

Thus, the number of ice blocks that can be stored in the freezer is 80 blocks of ice.
