RACTICE Uranium (molar mass = 283.03 g/mol) has the largest molar mass of any element naturally found on Earth. What is the mass
Marina86 [1]

Answer:

<h3>The answer is 2122.73 g</h3>

Explanation:

The mass of a substance given it's molar mass and number of moles can be found by using the formula

mass = Molar mass × number of moles

From the question

molar mass = 283.03 g/mol

number of moles = 7.5 mol

So we have

mass = 283.03 × 7.5 = 2122.725

We have the final answer as

<h3>2122.73 g</h3>

Hope this helps you

6. A 1,780kg car moving at 14m/s takes a turn around a circle with a radius of 50.0m.
m_a_m_a [10]

1) Centripetal acceleration: 3.9 m/s^2

2) Centripetal force: 6942 N

Explanation:

1)

For an object moving in uniform circular motion (=circular motion with constant  speed), the net acceleration is the centripetal acceleration, directed towards the centre of the trajectory and whose magnitude is given by

a=\frac{v^2}{r}

where

v is the speed

r is the radius of the circle

For the car in this problem, we have

v = 14 m/s is the speed

r = 50.0 m is the radius

Substituting, we find the acceleration:

a=\frac{14^2}{50.0}=3.9 m/s^2

2)

The net force acting upon the car is the centripetal force, also acting towards the centre of the circular path, and whose magnitude is given by

F=ma

where

m is the mass

a is the centripetal acceleration

For the car in this problem, we have:

m = 1780 kg is the mass

a=3.9 m/s^2 is the acceleration

Substituting, we find the centripetal force:

F=(1780)(3.9)=6942 N

Look at the distance-time graph below. It shows Angela's journey as she walks to the end of the road and back. The gradient repr
sineoko [7]

Answer:

The gradient here represents Angela's Velocity.

Explanation:

A distance-time graph has distance on its y-axis and time on its x-axis. Therefore, the gradient of the distance-time graph is given by the following formula:

Gradient = \frac{Change\ on\ y-axis}{Change\ on\ x-axis} \\\\Gradient = \frac{Distance\ Covered\ by\ Angela}{Time\ taken\ to\ cover\ the\  distance}\\\\Gradient = Angela's\ Velocity

Since the rate of change of distance is called the velocity.

<u>Therefore, the gradient here represents Angela's Velocity.</u>
