Answer:

The acceleration is 36.5853659

Explanation:

Acceleration is the change in velocity over the amount of time so for this it would be 15ms/.41s so the acceleration would be 36.5853659m/s^{2}

Answer:

When you climb, earth exerts gravitational force on pack in downward direction(pointing towards the center of earth).

In order to climb, you need to work against work done by gravity on the pack.

Hence work done by you = work done by gravity on pack  

                                       = Force x displacement = 70 x 30 = 2100 J.

 

So you need to do 2100 joules of work to lift your pack.

Power is the rate of work done.

Therefore power = work done by you/time(in seconds)

                           =     2100/600 =3.5 watts

Which evidence would confirm that a given rock later is newer than the layers around it. 1. It has been crumpled in folded, whil
s344n2d4d5 [400]

Answer:

Option 2. It cuts through all the other layers

Explanation:

Newer or younger rocks are usually formed from older rocks in the sense that older rocks are broken up, and their by product materials forming together to make younger rocks.

We can simply say that older rocks basically undergo recycling to form newer rocks.

Thus, looking at the given options,

For option 1, the newer rock cannot be crumpled while the others lie flat because it is the old one that is undergoing recycling and therefore the older one is the one that will be crumpled to give way for newer rocks. So it's not true.

For option 2, since they are from older rocks, they will clearly cut through the other layers of the old one because the old one will give way for the new one.

Option 3 is not true for the same reason given for option 1.

Option 4 is not true because there is no standard way in which it will be positioned

Insect A moves 5.0 m/min and insect B moves
mezya [45]

Answer:

insect B by 12m

Explanation:

30min = 1800s (times by 60)

5m/min x 30min = 150m

9cm/s x 1800s = 16,200cm = 162m

162m - 150m = 12m

you ask people to rate there depression on a scale of 1 to 10 their respnses are a (n)___in your study. a.variable b.discrete v
8090 [49]
The answer is A) variable. The depression level is a value that varies with the respondents and may inform you about the relationship between depression and other variables, such as alcohol use or sleep habits. It is also likely a discrete variable, since the answer is probably an integer (1, 2, ... 10), rather than a continuous spectrum (virtually any number between 1 and 10).

What force in Newton is required to accelerate a car starting from rest to 20 m/s in 15 seconds if the mass of the car is 2500 k
Lyrx [107]

We will solve this question using the second law of motion which states that force is directly equal to the product of mass and acceleration.

\sf \: F=ma

Where,

  • F is force
  • m is mass
  • a is acceleration

In our case,

  • F = ?
  • m = 2500 kg
  • a = 20m/s

\tt \: F_{net}  = 2500 \times 20 \\   \tt= 50000

<em>Thus, The force of 50000 Newton is required to accelerate a car of 2500 kg...~</em>

Which calculates the intensity of an electric field at a point where a 0.50 C charge experiences a force of 20. N?
tester [92]

Answer: 40\ N/C

Explanation:

Given

Magnitude of charge is q=0.5\ C

Force experienced is F=20\ N

Electric field intensity is the electrostatic force per unit charge

\therefore E=\dfrac{F}{q}\\\\\Rightarrow E=\dfrac{20}{0.50}\\\\\Rightarrow E=40\ N/C

Thus, the electric field intensity is 40\ N/C
