How high above the ground would a 2 kg object need to be in order to have 180 J

A boat is moving along the water. The forward thrust from the engines is 35,000 N. Water resistance is 20,000 N and air resistan

dedylja [7]

Answer:

The resultant force on the boat is 5,000 N

Explanation:

Given;

the forward thrust on the boat, Ft = 35,000 N

water resistance on the boat, Fw = 20,000 N

Air resistance on the boat, Fa = 10,000 N

The forces opposing the boat motion will be negative, while the force pushing the boat forward will be positive

The resultant force on the boat, Fr = Ft - Fw - Fa

Fr = 35,000 N - 20,000 N - 10,000 N

Fr = 35,000 N - 30,000 N

Fr = 5,000 N

Therefore, the resultant force on the boat is 5,000 N

Pepsin is a digestive enzyme that Pepsin is a digestive enzyme that splits maltose into monosaccharides. is manufactured by the

LUCKY_DIMON [66]

Answer:

The correct option is: begins the hydrolysis of proteins in the stomach

Explanation:

Pepsin is a protease enzyme that is synthesized by the stomach. It is the main gastric enzyme that helps in the digestion of proteins molecules present in the food.

The pepsin enzyme catalyzes the acid hydrolysis of the peptide bond in the proteins at a very low acidic pH of 1.5-2.0.

This enzyme becomes inactive at pH 6.0 and gets fully denatured or irreversibly inactivated as the pH increases to 8.0.

Where do most metamorphic processes take place?

inysia [295]

Answer:

Most metamorphic processes take place deep underground, inside the earth's crust.

Explanation:

During metamorphism, protolith chemistry is mildly changed by increased temperature (heat), a type of pressure called confining pressure, and/or chemically reactive fluids. hope this helps you :)

HELPPPPP MEEEEE PLEASE I NEED TO SUBMIT IN LESS THAN 10 MINSS

DerKrebs [107]

Answer:

X = 2146.05 m

Explanation:

We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.

We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:

X = Vt (1)

However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:

t = √2h/g (2)

Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:

t = √(2*2500)/9.8

t = 22.59 s

Now replacing into (1) we have:

X = 95 * 22.59

This is the distance where the package should be released.

Hope this helps
