Answer:

[tex]680\; \rm s[/tex].

Explanation:

Start by finding the total amount of energy required for melting that much ice.

[tex]\begin{aligned}&\text{Energy required for melting ice sample} \\ &= \text{Mass of Ice} \times \text{Specific Latent Heat of Ice} \\ &= 120\; \rm g \times 340\; \rm J \cdot g^{-1} = 4.08 \times 10^{4}\; \rm J \end{aligned}[/tex].

Hence, the heater would need to supply (at least) [tex]4.08 \times 10^{4}\; \rm J[/tex] of energy.

The power of the heater is [tex]60\; \rm W[/tex], which is equivalent to [tex]60\; \rm J \cdot s^{-1}[/tex], In other words, the heater is rated to supply [tex]60\; \rm J[/tex] of energy every second.

Amount of time it takes for the heater to supply [tex]4.08 \times 10^{4}\; \rm J[/tex] at [tex]60\; \rm J \cdot s^{-1}[/tex]:

[tex]\begin{aligned}\frac{4.08 \times 10^{4}\; \rm J}{60\; \rm J \cdot s^{-1}} = 680\; \rm s\end{aligned}[/tex].

Hence, it would take [tex]680\; \rm s[/tex] for the heater to melt the ice if the heater is insulated, and all the energy from the heater went to the ice.

Answer:

The laws of physics take the same form in all inertial frames of reference. As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.

Explanation:

Displacement involves direction and distance.  In this case, the deer has walked a distance of 17 + 12 = 29m but because of the South-then-North direction, the net displacement is only 17-12 = 5m.

Answer:

a condenser of capacitor 50 micro coulomb is charged to 10 volt the energy stored is 5×10−3J.

Answer:

The ratio of forces is 22 : 3.

Explanation:

Case I:

initial velocity, u = 35 mph

final velocity, v = 0

time, t = 15 ms

Case II:

initial velocity, u = 35 mph

final velocity, v = 0

time, t' = 110 ms

let the mass is m.

According to the Newton's second law, the force is given by the rate of change of momentum.

So

[tex]F =\frac{m(v-u)}{t}\\\\F'= \frac{m(v-u)}{t'}\\\\So, \frac{F}{F'} =\frac{t'}{t}\\\\\frac{F}{F'}=\frac{110}{15}=22:3[/tex]

Answer:

50 N.

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 5 Kg

Coefficient of friction (μ) = 0.36

Normal reaction (N) =?

Next, we shall determine the weight of the body. This can be obtained as follow:

Mass (m) = 5 Kg

Acceleration due to gravity (g) = 10 m/s²

Weight (W) =?

W = mg

W = 5 × 10

W = 50 N

Finally, we shall determine the normal reaction. This can be obtained as follow:

Weight (W) = 50 N

Normal reaction (N) =?

Normal reaction = weight of the body

N = W = 50 N

Thus, the normal reaction acting on the body is 50 N

Answer:

Explanation:

I'm assuming you missed the decimal point in the initial velocity and that it should be 4.0 m/s. If after a half of a second it is moving a tiny bit slower, it would be because of air resistance. You can only neglect air resistance if the problems you are doing tell you neglect it.

Answer:

The current through the wire is equal to 0.8 A.

Explanation:

Given that,

The length of a copper wire = 2 m

Potential difference = 24 mV

The current through the wire is 0.40 A.

The new potential difference is 48 mV.

We need to find the current through the wire.

As the potential difference is doubled for second wire. So the new current will be :

I' = 2I

= 2 × 0.4

= 0.80 A

So, the current through the wire is equal to 0.8 A.

Answer:

Explanation:

There are a couple of things we need to clear up before we start the problem. First of all, we are given an angle in the problem along with an initial velocity. BUT this is what I call a "blanket" velocity: it is neither the upwards velocity nor is it the horizontal velocity. In order to find either the upwards velocity or the horizontal velocity we have to use either the sin or the cos function, respectively. Since we are working ONLY in the y-dimension, which is up and down, we use the sin function along with the given velocity to find the upwards velocity of the ball. Secondly, we have to know that the final velocity at the max height of the ball is 0. So here is what we have:

v₀ = 12sin14 so

v₀ = 2.9 m/s

a = -9.8 m/s/s

v = 0 m/s

Δx = ??? m

The equation we need is

v² = v₀² + 2aΔx and filling in:

0 = (2.9)² + 2(-9.8)Δx and

0 = 8.4 - 2.0 × 10¹Δx and

-8.4 = -2.0 × 10¹Δx so, to the correct number of sig dig,

Δx = 170 m
