Answer:
Acceleration of proton will be 
Explanation:
We have given a proton is placed in an electric field of intensity of 700 N/C
So electric field E = 700 N/C
Mass of proton 
Charge on proton 
So electric force on the proton 
This force will be equal to force due to acceleration of the proton
According to newton's law force is given by F = ma
So 

So acceleration of proton will be 
Saturn's rings are made of billions of pieces of ice, dust and rocks. Some of these particles are as small as a grain of salt, while others are as big as houses.
Answer:
Find answers below.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;
1. Speed: Jackson ran 5k in 24 minutes.
2. Velocity: A storm is travelling 25 km/hour eastward.
3. Speed: John walked 420 m in 17.5 seconds.
4. Velocity: Zart moved the desk 34 cm to the left.
5. Speed: A hurricane travels 360 km in 15 hours.
6. Speed: Meredith runs 400 meters in 50 seconds.
7. Velocity: Stephen Jay swims 110 m towards the shore in 72 seconds.
8. Velocity: Vince throws a baseball 38 m from third base to first base in 1.7 seconds.
Answer:
6
Explanation:
The mean is the same thing as the average. To find the average, add up all the numbers and then divide the sum by amount of numbers you added together.
First add up all the numbers.
7 + 5 + 10 + 2 = 24
Then divide by the number of numbers you added together. In this case we added 4 numbers together.
24 ÷ 4 = 6
