URGENT The nuclear equation is incomplete what particle completes the equation.

Physics
1 answer:
zimovet [89]4 years ago
3 0

Answer: A

Xenon 138

Explanation:

In the attached nuclear reaction, the sum of the mass number in LHS is

239 + 1 = 240

While the Atomic number = 54 + 0 = 54

The sum of the mass number in the RHS is 100 + 2(1) = 102

While the sum of the atomic number is

40 + 0 = 40

The mass number of the missing element is

240 - 102 = 138

While the Atomic number of the missing element is

94 - 40 = 54

Nuclear reaction at equilibrium, the mass number and the atomic number at LHS must be equal to RHS

The missing element is Xenon 138 with atomic number of 54

Therefore, when the Plutonium is bombarded with a neutron, the result of the reaction is the production of Zirconium 100 and Xenon 138 with the bombardment of two neutrons

A certain brand of hot-dog cooker works by applying a potential difference of 120 V across opposite ends of a hot dog and allowi
ivanzaharov [21]

Answer:

The time it will take to cook three hot dogs simultaneously is 2.5 minutes

Explanation:

Here we have, the Energy of electric heating given by Joule heating that is;

P = IV = 120×10 = 1200 J/s = 1.2 kJ/s

Since the energy required to cook one hotdog = 60.0 kJ we have

Energy required to cook three hot dogs = 3 × 60.0 kJ  = 180.0 kJ

Therefore, the time required to cook the three hot dogs is

(180.0 kJ)/(1.2 kJ/s) = 150 s

The time it takes to cook three hot dogs simultaneously is

150 seconds or 150/60 minutes which is 2 minutes 30 seconds or 2.5 minutes

To view an interactive solution to a problem that is similar to this one, select Interactive Solution 7.24. A 0.0146-kg bullet i
Vinil7 [7]

Answer:

0.25223 seconds.

Explanation:

m_1 = Mass of bullet = 0.0146 kg

m_2 = Mass of block = 2.55 kg

v = Combined velocity

u_1 = Velocity of bullet = 816 m/s

g = Acceleration due to gravity = 9.81 m/s²

As linear momentum is conserved

m_1u_1 + m_2u_2 =(m_1 + m_2)v

Now u_2=v as the block (with the bullet in it) reverses direction and rises,

m_1u_1 + m_2v =(m_1 + m_2)v\\\Rightarrow m_1u_1=(m_1 + m_2)v-m_2v\\\Rightarrow 0.0146\times 816=(0.0146 + 2.55)v-(-2.55v)\\\Rightarrow 11.9136=2.2646v+2.55v\\\Rightarrow 11.9136=4.8146v\\\Rightarrow v=\frac{11.9136}{4.8146}\\\Rightarrow v=2.47447\ m/s

Equation of motion

v=u+at\\\Rightarrow t=\frac{v-u}{a}\\\Rightarrow t=\frac{2.47447-0}{9.81}\\\Rightarrow t=0.25223\ s

The time t is 0.25223 seconds.

PLEASE HELP MEEE!! I WILL MARK YOU AS BRAINLIEST AND EVERYTHING!! THIS IS DUE TODAY AND MY GRADES ARE AT STAKE!:(
irina [24]

Answer:

They will be 140 miles apart 8 hours after the first boy started the trip or 6 hours after the second boy started the trip.

Explanation:

x = the time that the first boy travels at 14 mph

x - 2 = the time the second boy travels at 14 mph

140 the distance between them

Since one travels north and the other east (their roads are perpendicular) the distance between them can be calculated using Pythagorean Theorem

(14*x)^2 + ((x-2)*14)^2 = 140^2

the solutions of the quadratic equation are

x1 = - 6 is not the solution since x > 0

x2 = 8 h is the solution
