The table shows the decay in a 59 g sample of bismuth 212 overtime.
Vikki [24]

Answer: C

14.75g

Explanation:

Given that the half life time = 60.5s

Let No = initial mass = 59g

N = decayed mass

At time t = 0, No = 59g

At time t = 60.5s,

N = No/2 = 59/2

= 29.5g

At time t = 121

N = 29.5/2 = 14.75g

Therefore N = 14.75g

What is true about the force between charges?
shusha [124]

Answer:

The statements A and D are true

The statements B and C are false

Explanation:

The force between charges can be explained by the Coulomb's Law.

According to Coulomb:

1 - Like charges always repel each other

2- Unlike or opposite charges always attrack each other

3- Force between 2 charges is given by:

F=k\frac{q_1q_2}{r^2}

where F is the force between 2 charges and r is the distance between 2 charges.

We can see that Force F is inversely proportional to the distance r

Which means that when F increase, r decreases and when F decreases, r increases

A 700700700-Newton rightward net force is being applied to a 101010-kg object. What is the magnitude of the rightward accelerati
lara [203]

Answer:

a = 70 m/s²

Explanation:

From Newton's second law of motion, we know that when an unbalanced force is applied to an object it produces acceleration in the object in the direction of the force. Therefore,

F = ma

a = F/m

where,

a = rightward acceleration = ?

F = Rightward net force = 700 N

m = Mass of Object = 10 kg

Therefore,

a = 700 N/10 kg

<u>a = 70 m/s²</u>
