What is Earth's position in the solar system?

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for

svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

F = m x a

F = force on body

m = mass of body

a = acceleration of the body

But we know that acceleration is the change in velocity with time of a body;

a = $\frac{change in velocity }{time}$

F = m x $\frac{V}{t}$

V is the velocity

t is the time taken

F = $\frac{75 x 4.4}{3.1}$ = 106.5N

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t

Naddik [55]

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

SOMEONE PLEASE HELP!!!

MatroZZZ [7]

Answer:

The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.

Explanation:

During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.

I hope I have helped you, can you put that this is the smartest answer please.
