**Answer:**

The magnetic flux density** **is

**Explanation:**

**Given that,**

Distance = 0.36 m

Current = 3.8 A

**We need to calculate the magnetic flux density **

**Using formula of magnetic field**

Where,

r = radius

I = current

Put the value into the formula

**Hence, The magnetic flux density is **

She does work from the moment she touches the book until she lets it go. Work is anything that requires energy. Therefore, she is working as she picks up the book, carries it, and when she is lifting it onto the shelf.

Answer:

20 metres

Explanation:

Given that the area of a triangle is 30 square metres (m²). Using the equation A = 1/2bh, this is the formula for the triangle.

where b is base and h is height

Given that b = 3 metres.

To calculate h, Substitute b and A into the equation

30 = 1/2 × 3 × h

3h = 60

h = 60/3

h = 20 m

Therefore, h is equal to 20 metres

**Answer:**

the density of gold is 19.3 g/cc

**Answer:**

see below

**Explanation:**

according to newton's second law of motion,

F = MA

where F is the resultant force

m is the mass

a = acceleration

so suppose the mass of the bowling ball is 10 kg

and the mass of golf ball is 1 kg

and the force applied on both of them is 5 N

substitute the values in the formula

for the bowling ball

5 = 10 x a

a = 0.5 ms²

for the golf ball

5 = 1 x a

a = 5 ms²

so which accelerated more the golf ball right?

so last option is the answer
