For every 120 joules of energy input a car wastes 85 joules , find the useful energy output of the car ?

Physics
1 answer:
Tamiku [17]3 years ago
6 0

Answer:

35 Joules

Explanation:

Applying

Input Energy(Q) = Useful energy output(U)+Wasted Energy(W)

Q = U+W.............................. Equation 1

Make U the subject of the equation

U = Q-W................... Equation 2

From the question,

Given: Q = 120 Joules, W = 85 Joules

Substitute these values into equation 2

U = 120-85

U = 35 Joules

∠1 and ∠2 are vertical angles. If m∠1 = (17x + 1)° and m∠2 = (20x – 14)°, find m∠2. Answer with "m∠2=_"
Bingel [31]

Answer:

m<2 = 86

Explanation:

Vertical angles means the angles are equal to each other so:

<1 = <2

17x + 1 = 20x - 14

17x - 20x = -14 - 1

-3x = -15

x = 5

m<2:

20x - 14

20(5) - 14

100 - 14

86

At a distance r1 from a point charge, the magnitude of the electric field created by the charge is 395 N/C. At a distance r2 fro
Ksenya-84 [330]

Answer:

r₂/r₁ = 1.82

Explanation:

The electric field due to a point charge, has the following expression:

E =\frac{k*q}{r^{2}}

For a distance r₁, the magnitude of the electric field is 395 N/C, so we can solve for r₁², as follows:

r₁² = \frac{k*q}{395 N/C} } (1)

For a distance r2, the magnitude of the electric field is 119 N/C, so we can solve for r₂², as follows:

r₂² = \frac{k*q}{119 N/C} }

We can find the quotient r₂/r₁, from (1) and (2):

r₂/r₁ =\sqrt{395/119} = 1.82
