Answer: 3.889N/m

Explanation:

f=(1/2)*√k/m

f=n/t

f= 21/3.3=6.4Hz

6.4*2=√k/m

12.73=√k/m

12.73^2=k/m

162.0529=k/m

Since m=24g

Convert g to kg

m=24/1000

m=0.024kg

K=162.0529*0.024

K=3.889N/m

Which is most likely a covalent compound?<br><br> LiF<br> MgS<br> NH3<br> CaCl2
Artemon [7]

Answer:

NH₃

Explanation:

The compound that is covalent from the given choices is NH₃.

Covalent compounds are usually formed between two atoms with similar values of electronegativities such that the difference is very small or zero.

  • This bond type involves the sharing of electrons between two atoms with similar electronegativities.
  • Nitrogen and hydrogen forms stable configuration that are isoelectronic with noble gases by sharing their valence electrons.
  • The 3 hydrogen electrons are enough to make nitrogen isoelectronic with neon.
  • Also, the nitrogen with 3 lone pairs of electrons provides the bonding hydrogen with needed electrons to attain a structure similar to helium.

A 125kg man buy a 6kg watermelon, a 3kg cantaloupe, and 6kgs of potatoes, he walks home with his purchases in a large bag. His w
Stells [14]

Answer:

350N

Explanation:

Given parameters:

Mass of the man = 125kg

Mass of the watermelon = 6kg

Mass of cantaloupe  = 3kg

Mass of potatoes  = 6kg

Acceleration  = 2.5m/s²  

Unknown:

Force required to get home  = ?

Solution:

To find this force we use;

    Force  = mass x acceleration

mass  = 125 + 6 + 3 + 6  = 140kg

 So;

      Net force = 140 x 2.5  = 350N

g A change in the initial _____ of a projectile changes the range and maximum height of the projectile.​
docker41 [41]

Answer:

Velocity.

Explanation:

Projectile motion is characterized as the motion that an object undergoes when it is thrown into the air and it is only exposed to acceleration due to gravity.

As per the question, 'any change in the initial velocity of the projectile(object having gravity as the only force) would lead to a change in the range as well as the maximum height of the projectile.' To illustrate numerically:

Horizontal range: As per expression:

R= (u^{2}*sin2θ)/g

the range depending on the square of the initial velocity.

Maximum height: As per expression:

H= (u^{2} * sin^{2}θ )/2g

the maximum distance also depends upon square of the initial velocity.
