Earth distance to the Sun is about 40 times the Moon's distance from earth.

<u>Explanation:</u>

  • The Earth's distance from the Sun is about 93 million miles. When it expressed in Km, it is 150 million Km.
  • The Moon's distance from Earth is 238,855 miles. When it is 40 times then it will approximately equal to 93 million miles.
  • The Sun's distance from Venus is 67.237 million miles. The Sun's distance from mercury is 35.832 million miles.

Darya [45]

Answer:

The magnitude of each force is 1309 N and 105 N

Explanation:

The reaction at each lifter due weight and overturning effect (R₁, R₂) is given as:

R_1=\frac{150}{2} cos(45^0) +\frac{1.5}{2+1.5} *150sin(45^0)=53.03 +45.46=98.49kg\\R_2=\frac{150}{2} cos(45^0) -\frac{1.5}{2+1.5} *150sin(45^0)=53.03-45.46=7.57kg

g = 9.8 m/s²

R_1=98.49*g=98.49*9.8=925.904N\\R_2=7.57*g=7.57*9.8=74.186N

Resolving the reactions to the vertical direction, we get:

R_{1v}=\frac{R_1}{cos(45^0)} =\frac{925.904}{cos(45^0)}=1309N\\ R_{2v}=\frac{R_2}{cos(45^0)} =\frac{74.186}{cos(45^0)}=105N\\

The magnitude of each force is 1309 N and 105 N

Refer to the graphs to compare the rate of this reaction with and without a catalyst. 
expeople1 [14]
A catalyst lessens the energy for a reaction so it can speed up so the  catalyst is not used up in the end of the reaction so the answer would be D.

Periods ughhh
Lerok [7]

Answer:

1. acceleration value

2. 20 m

3a. when you throwing somethinb upward

3b. when a thing reach maximum height after throwing upward

4. (entire only) velocity = diaplacement/ time = 0/91 = 0

speed = distance/time = 200/91 = 2.2 m/s

5. (40-20)/4 = 5 m/s²

6. displacement using phytagoras get 50 m

velocity = displacement/time = 50/(6+4) = 5 m/s

7. 0, it turn back to the base

8. speed = distance/time = (240*2)/(4+6) = 48 km/h

9. s = (4+14)*3/2 =27 m

A force of 6N is exerted on a cart that is carrying a rock and produces an acceleration of 2 m/s2. If the cart has a mass of 1 k
vaieri [72.5K]
If you use the equation F=ma and re-arrange it to get m = F/a, you'll get the total mass. Then you have to subtract the mass of the cart from the total mass to get the mass of the rock. 

Thus, m = 6N over 2m/s^2. The total mass will then be 3kg. Subtracting 1kg from the total mass will then yield you 2kg, which is the mass of the rock. Hope this helps.
