Answer:
They can give us information and energy.
Explanation:
Fossils can be burned to give us energy and fuel. They can also give us information about the earths history.
Answer:
Mass of the vehicle and small bug.
Explanation:
- By Newton's third law, force on bug and vehicle will be same when they collide with each other irrespective of their masses.
- But according to Newton's second law, force is mass times acceleration. Since the force on each mass is same, the smaller mass will accelerate more and the heavier mass will accelerate less for the same force.
- Therefore the acceleration of bug will be very greater than vehicle as the mass of the bug is very small as compared to vehicle.

#SPJ10
Answer:
#include <iostream>
#include <vector>
using namespace std;
int main() {
const int NUM_GUESSES = 3;
vector<int> userGuesses(NUM_GUESSES);
int i = 0;
int uGuess = 0;
for(i = 0; i <= userGuesses.size() - 1; i++){
cin >> uGuess;
userGuesses.at(i) = uGuess;
}
cout << endl;
return 0;
}
Explanation:
First inbuilt library were imported. Then inside the main( ) function, 3 was assigned to NUM_GUESSES meaning the user is to guess 3 numbers. Next, a vector was defined with a size of NUM_GUESSES.
Then a for-loop is use to receive user guess via cin and each guess is assigned to the vector.
Answer:
speed of the arrow as it leaves is 41.05 m/sec
Explanation:
We have given mass m = 0.285 kg
Average force F = 182 N
Distance traveled d = 1.32 m
We know that work done = force distance
Sp work done =
Now according to work energy theorem work done will be equal to kinetic energy
So
v = 41.05 m/sec
So speed of the arrow as it leaves is 41.05 m/sec
