On a small planet, an astronaut uses a vertical force of 175 newtons to lift an 87. 5-kilogram boulder at constant velocity to a

height of 0. 350 meter above the planet’s surface. What is the magnitude of the gravitational field strength on the surface of the planet?.

Since the boulder is raised with constant velocity, the net force on the boulder is zero, so that the boulder has weight 175 N on this planet. If its mass is 87.5 kg, then the acceleration due to gravity is g such that

175 N = (87.5 kg) g   ⇒   g = (175 N) / (87.5 kg) = 2.00 N/kg = 2.00 m/s²

Compare the covenant God made with Abraham to the new covenant
Karo-lina-s [1.5K]

The correct answer to this open question is the following.

Although you did not attach options for this question, we can say the following.

The original (first) covenant God made with Abraham was the promise of God to bless the descendants of Abraham. God blessed Abraham and told him that he was going to be the "father" or leader of many tribes. In Genesis, the first book of the Old Testament, God told Abraham to travel to the promised land of Cannan, but he had to make sure that his people would be faithful and loyal to God.

In comparison, the Second Covenant is the one that is referred to in the New Testament, when God, who loves his creatures, sent his own son Jesus to help humans. God promises humans that he will forgive all their sins if they followed Jesus' teachings.

A photographic stop bath contains 160ml of pure acetic acid.
NeTakaya

Answer:

Solving for the Percent by Volume

The v/v concentration of acetic acid in the stop bath is 24.6%.

Explanation:

To answer the question, we need to identify certain information stated in the question. Let us write down what’s given:

Volume of solute = 160 mL

Volume of solution = 650 mL

Next, we need to determine what is required, in this case, the percent by volume. Now, let us look at the formula:

v/v concentration = (solute volume / volume of the solution) * 100

Solution:

Percent by Volume = (160 / 650) * 100

Percent by Volume = 0.2461538461538462 * 100

Percent by Volume = 24.61538461538462

Rounded off = 24.6%

Therefore, the final answer is 24.6%

masya89 [10]

Chávez's claim that the autonomic nervous system is too diffuse and slow to explain rapid and differentiated emotional responses is <u>wrong</u>.

<h3>The autonomic nervous</h3>

This system regulates certain body processes such as blood pressure and respiratory rate. It works automatically (autonomously) without the person's conscious effort.

The path of an autonomic nerve involves two nerve cells. One of them is located in the brain stem or spinal cord. It is connected by nerve fibers to another cell, located in a group of nerve cells (called autonomic ganglia). Nerve fibers from these ganglia connect with internal organs.

With these information, we can conclude that Chávez's claim that the autonomic nervous system is too diffuse and slow to explain rapid and differentiated emotional responses is <u>wrong</u>.
