Why collaboration in science is critical to success in the scientific community
Marianna [84]
Collaboration in science is important because if only one scientist does an experiment, and gets a result, he/she could have messed. So this is where collaboration comes in. A few other scientists could try the experiment, and if they get the same answers, the result may be proven correct.


Hope this helped!

A sled that has a mass of 8 kg is pulled at a 50 degree angle with a force of 20 N. The force of friction acting on the sled is
vitfil [10]

The acceleration of the sled will be 1.30 m/s². Force is defined as the product of mass and acceleration.

<h3>What is force?</h3>

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Given data;

m(mass of sled)=8 kg

Θ is the inclination of force= 50°

Force of friction,f=2.4 N.

The applied force at the given angle is resolved into the two-component as;

\rm F_h=F cos \theta \\\\ F_h= 20 cos 50 ^0 \\\\ F_h= 12.85 \ N

\rm F_v=F sin \theta \\\\  F_v=20 sin 50^0 \\\\   F_v=15.32 \ N

The net vertical force is zero;

\rm F_N=mg-Fsin50^0 \\\\ \rm F_N=8 \times 9.81 -15.32 \\\\ F_N=63.1 \ N \\\\

From Newton's second law the net force as;

\rm \sum F_{net}=ma \\\\ Fcos 60^0-f =ma \\\\ a=\frac{12.855-2.4}{8} \\\\a = 1.30 \ m/s^2

Hence, the acceleration of the sled will be 1.30 m/s².

How could you group pennies,nickels, and dimes together
julsineya [31]

There isn't a direct answer to this, but I can show you!

This is how you group Pennies, Nickels, and Dimes.

1 Penny= 1 cent.

1 Nickel= 5 cents.

1 Dime= 10 cents.

Imagine if there was 5 pennies, 3 dimes, and 8 Nickels.

That might seem like a lot of numbers, but it's pretty simple!

You know how pennies are worth 1 cent? If we had 5 pennies, that would be 5 cents.

1+1+1+1+1=5 cents.

Then, we have 3 dimes. Dimes are each 10 cents.

So, 10x3 (If you know multiplication,  if not, you will learn it later) :)

10+10+10=  30 cents.

Now, nickels. We have 8 nickels! Remember, each nickel is 5 cents.

5+5+5+5+5+5+5+5=

40 Nickels.

Now add all of the coins up.

5 cents + 30 cents + 40 cents = 75 cents!

I hope this helped! If you need more help, you can ask me. :)

A wrench is accidentally dropped at the top of an elevator shaft in a tall building. (a) How many meters does the wrench fall in
RUDIKE [14]

Answer:

11.25m

Explanation:

s = ut +  \frac{1}{2} a {t}^{2}  \\  = 0 \times 1.5 +  \frac{1}{2} \times 10 \times   {1.5}^{2}  \\  = 5 \times 2.25 \\  = 11.25
