The number of oscillations of the toy in a second is 1.25.

<h3>What is frequency?</h3>

This is the number of complete oscillation of an object is a given period.

The given parameter:

Frequency of the toy, F = 1.25 Hz

The frequency of an object is calculated as follows;

$f = \frac{n}{t} \\\\$

where;

n is the number of oscillations
t is the time of motion

The number of oscillations of the toy in a second is calculated as follows;

$1.25 = \frac{n}{1} \\\\n = 1.25$

Scrat [10]

Answer:

Power required will be 7.2 watt

Explanation:

We have given battery of Barble jeep is 6 volt

So potential difference V = 6 volt

Resistance of electric motor R = 5 ohm '

We have to find the power motor using to drive the jeep

Power is given by $P=\frac{V^2}{R}$ , here V is voltage and R is resistance

So $P=\frac{V^2}{R}=\frac{6^2}{5}=7.2watt$

A 50,0 g silver spoon at 20.0°C is placed in a cup of coffee at

My name is Ann [436]

The heat capacity of the silver spoon at the given temperature difference is 817.65 J.

<h3>Heat capacity of the silver spoon</h3>

The heat capacity of theb silver spoon is the quantity of heat absorbed by the silver spoon. The heat capacity of the silver spoon at the given temperature difference is calculated as follows;

Q = mcΔθ

where;

m is mass of the spoon
c is specific heat capacity of silver = 0.237 J/g⁰C
Δθ is change in temperature

Q = 50 x 0.237 x (89 - 20)

Q = 817.65 J

Thus, the heat capacity of the silver spoon at the given temperature difference is 817.65 J.

A bike with 15cm diameter wheels accelerates uniformly from rest to a speed of 7.1m/s over a distance of 35.4m. Determine the an

Finger [1]

Answer:

9.47 rad/s^2

Explanation:

Diameter = 15 cm, radius, r = diameter / 2 = 7.5 cm = 0.075 m, u = 0, v = 7.1 m/s,

s = 35.4 m

let a be the linear acceleration.

Use III equation of motion.

v^2 = u^2 + 2 a s

7.1 x 7.1 = 0 + 2 x a x 35.4

a = 0.71 m/s^2

Now the relation between linear acceleration and angular acceleration is

a = r x α

where, α is angular acceleration

α = 0.71 / 0.075 = 9.47 rad/s^2

Is glass weigh more than wood

inn [45]

It depends how large the object is. But, if it is 2 by 4, most likely the wood sieges more than the glass. Hope this helps.
