Which of these are the primary components in an automobile battery?

Darin skateboarded to the north at 4 m/s. In 5 seconds, he sped up to 7 m/s. What was his acceleration?

Julli [10]

To solve this problem we can use following equation.

v =u + at

Where v is the final velocity (m/s), u is the initial velocity (m/s), a is the acceleration (m/s²) and t is the time taken (s).

v = 7 m/s
u = 4 m/s
a = ?
t = 5 s

By applying the equation, we can get
7 m/s = 4 m/s + a x 5 s
3 m/s = a x 5 s
a = 0.6 m/s²

Hence, the acceleration is 0.6 m/s² towards north.

Answer is "C".

In stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down p to amino acids. Stomach ju

Butoxors [25]

$\huge{ \underline{ \boxed{ \bf{ \green{Answer:}}}}}$

Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down proteins to amino acids.

✤ So, Fill the blank with proteins.

<h3>Explanation:-</h3>

Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.

What is 10 times as many as 1 hundred is blank hundred or blank thousand ?

Rama09 [41]

10 times as many as 1 hundred is 10 hundred or 1 thousand.

This is the question of simple multiplications related to a place value system.

The given equation in unit form can be rewritten as:

10 × 1 × 100 = (X × 100) or (Y × 1000)

Arranging in two parts, we get,

10 × 1 × 100 = X × 100 ........(1)

10 × 1 × 100 = Y × 1000 ........(2)

Now, calculating the value of X and Y,

From equation (1), we get,

10 × 1 × 100 = X×100

or, 1000 = X × 100

or, X = 10

Hence, 10 times as many as 1 hundred is 10 hundred.

Similarly, from equation (2). we get,

10 × 1 × 100 = Y × 1000

or, 1000 = Y × 1000

or, Y = 1

Hence, 10 times as many as 1 hundred is 1 thousand.

Therefore, 10 times as many as 1 hundred is 10 hundred or 1 thousand.
