5 0

p(1) = -16 x (1)³ + 3 x (1)² + 8 x 1 + 4

= -16 + 3 + 8 + 4

= -16 +16

=0

Akimi4 [234]
<h3><u>Answer;</u></h3>

= 480 Joules

<h3><u>Explanation;</u></h3>

We use the formula, Q - W = ΔU

Where, Q = Heat transferred to the system

W = Work done by the system

ΔU = Change of internal energy.

As per the question, Q = 658 J

ΔU = 178 J

Thus, W = Q - ΔU = (658 - 178) J = 480 J.

The energy used to do work by the system is 480 J.

Nets used to catch falling boulders on the side of rocky hillside roadways
Natalija [7]

Answer:

more time to change the momentum of falling rocks

Explanation:

Momentum is related to "mass in motion." So, if an object is moving, then it has momentum as it has its mass in motion. The amount of momentum is dependent upon how much and how fast the object is moving.

If an object is moving slowly, it means that the object is losing momentum.

Nets used to catch falling boulders on the side of rocky hillside roadways  are more effective than rigid fences because their breakage is reduced by more time to change the momentum of falling rocks.

How does eating food produced locally benefit the environment?
fomenos

Answer:

Eating food produce locally makes it where big trucks don't have to bring it to the restaurant  

Explanation:

When the big trucks drive it they release pollutants into the air so therefore when you get stuff produced locally you don't have the big trucks polluting the air. So therefore it is better for the environment.

at t=T/6, total distance covered= 2*pi*r/6  and  displacement= r

 difference of them = 2*t
so, 2*pi*r/6- r =2(1/6)=1/3

r=1/(pi-3)=7.062

A satellite in a nearly circular orbit is 2000 km above earth's surface. the radius of earth is approximately 6400 km. if the sa
Ann [662]
Velocity is computed using the formula:

v= \frac{d}{t}
Where:
V = speed
d = distance traveled
t = time/period

First you need to consider that the orbit is circular. To get the measurement or the distance going around Earth, you will need to get the circumference of the path. 

C = 2 \pi r

Where:
C = circumference
π = 3.14
r = radius


The Earth has a radius of 6,400km, but you also need to consider that the satellite is orbiting above the surface of the Earth, so you add in the 2,000km to that radius. 

r = 6,400Km + 2,000Km = 8,400Km

Next step is to insert that into our circumference formula:

C = 2 \pi r
C = 2 \pi 8,400Km
C = 52,778.76 Km

The distance traveled would then be 52,778.76Km

Now that we have the distance, we can then get the velocity:

v= \frac{d}{t}
v= \frac{52,778.76Km}{12hrs}
v= 4,398.23km/hr

The speed of the satellite is 4,398.23km/hr.
