2. Co<u>n</u>ductor
3. Flow
4. Thermal ener<u>g</u>y (g underlined)
5. Elect<u>r</u>ic current
6. Insulator
7. Light energ<u>y</u>
8. El<u>e</u>ctric circuit
The underlined letters are, e, n, g, r, y, e which can be rearranged to spell energy
Explanation:
1. Sound energy is the wave form of mechanical energy that is transferred by the vibration of the of the medium through which it propagates
2. An electrical conductor is used to conduct electricity from one point to another
3. An object or material flows when it has a smooth motion towards a given direction, such as a river
4. Thermal ener<u>g</u>y is the form of energy that is given off by a body as sensible heat that can be measured as a temperature by a thermometer
5. Electric current is the electricity in a circuit
6. An insulator is a material that limits the flow of electricity or heat
7. Light energy is the form electromagnetic energy which the eye can sense
8. An electric current flows an electric circuit which consist of a source of electricity and an path through which the electric current can easily flow.
Answer:
Fran's upstream time = 37.93 hrs
Fran's downstream time = 30.13 hrs
Explanation:
given data
speed in still water = 2.62 km/h
River flows = 0.3 km/h
Fran to swim upstream = 88 km
solution
we will apply here distance formula that is
distance = speed × time ...................1
put here value
so here
Fran's upstream speed = 2.62 km/h - 0.3 km/h = 2.32 km/h
Fran's downstream speed = 2.62 km/h + 0.3 km/h = 2.92 km/h
so
Fran's upstream time = = 37.93 hrs
Fran's downstream time = = 30.13 hrs
Answer:
The mass of the another block is 60 kg.
Explanation:
Given that,
Mass of block M= 100 kg
Height = 1.0 m
Time = 0.90 s
Let the mass of the other block is m.
We need to calculate the acceleration of each block
Using equation of motion
Put the value into the formula
We need to calculate the mass of the other block
Using newton's second law
The net force of the block M
....(I)
The net force of the block m
Put the value of T from equation (I)
Put the value into the formula
Hence, The mass of the another block is 60 kg.
