Answer:
Explanation:
Distance travelled by sound in going to target( insect ) and returning back = 2d ,d is distance of target .
time t = .06 s
speed = distance / time
344.9 = 2d / .06
d = 10.35 m
Answer:
3.88kg
Explanation:
From the question given, we obtained the following data:
W = 32N
g = 8.25 m/s2
M =?
W = M x g
M = W/g
M = 32/8.25
M = 3.88Kg
The mass of the object is 3.88kg
To solve this problem, apply the concepts given from Ohm's Law. From there we will obtain the derivative of the function with respect to time and with the previously given values we will proceed to find the change in current as a function of the derivative
Here
I = Current
V = Voltage
R = Resistance
Taking the derivative we will have,
Our values are given as,
Replacing we will have that
Rearranging to find the current through the time,
Therefore the change of the current is -0.000026A per second

<h3><u>Answer</u>;</h3>
A) 84 calories
<h3><u>Explanation</u>;</h3>
- Specific Heat Capacity is the energy, transferred as heat, that is required to raise the temperature of one gram of a substance by one degree Celsius.
- Quantity of heat = mcΔt; Where m is the mass in kilograms, c is the specific heat capacity and Δt is the change in temperature.
<em>Mass = 10 g, specific heat capacity = 0.21 cal g°C, and Δt = 10 °C</em>
<em>Therefore;</em>
<em>Heat = 10 × 0.21 cal g°C × 40 °C</em>
<em> = </em><u><em>84 calories</em></u><em> </em>
