Explanation

Explanation

A Newton (N) is the unit of force in the International System of Units (SI).

Force (F) is equal to mass (m) times acceleration (a): F = ma.

"That gives a 1 kg body an acceleration of 1 m/s²".

Using F = ma, if m = 1 kg and a = 1 m/s², then F = 1 kg × 1 m/s² = 1 N.

Explanation

A quadratic equation is defined as an equation where the highest exponent (degree) of the variable is 2, like ax² + bx + c = 0.

Hence, its degree is 2.

Explanation

Ernest Rutherford showed (1919) that nitrogen under alpha-particle bombardment ejects what appear to be hydrogen nuclei.

By 1920 Ernest Rutherford had accepted the hydrogen nucleus as an elementary particle, naming it proton.

while

Electron was discovered by J. J. Thomson in 1897.

Explanation

A catalyst is a substance that speeds up a chemical reaction without being consumed or altered.

Catalysts increase the rate of reaction by lowering the activation energy required for the reaction to occur.

Explanation

Step 1: Let's denote the age of the youngest child as x.

The ages of the 5 children will be x, x + 3, x + 6, x + 9, and x + 12.

Step 2: Calculate the sum of their ages.

x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

Step 3: Simplify the equation.

5x + 30 = 50

Step 4: Solve for x.

5x = 20

x = 4
