Introduce my mother + English composition Our family is living a happy life. This is due to my mother, who is in her forties and has traditional beauty and modern consciousness. She has received higher education and a sense of family responsibility. She sacrificed her career for us and is good at accepting new things. Recently, she has become a stock fan and a football fan. I love my mother. We have many common interests and we have become close friends

My mother is 38 years old, she has a pair of black eyes and black hair, she does not look very beautiful to be very gentle, she has a good-looking nose and a little fat, look carefully, there are some wrinkles on his face, that is worried about me, his head also has some white hair, I think that should be the same. My mother may not be very good in other people's eyes, but in my heart, she is great

Mom, I want to speak English composition to you

My Dear Mother,
I have something to tell you but I have no courage to talk to you about this face by face so I write this letter to you .
Do you know I am under stress?I have no time to relax.You always force me to join many classes and extra-curricular activities.I rather hate these things but I can't say no.Since I don't want to let you feel disspointed.Could you pleased to help me
I have no enough time for revision and I got a poor result in the exam.I am shamed and fear to tell you .You didn't score me but encouraged me when you received my exam paper.At that moment,I was so touching.I felt your loves that you gave me .
Mom ,I love you very much .I know you think same as me.Athought sometimes I lose my temper ,I still love you .
Love,
your daughter/ son

The tolerance of the arithmetic sequence {an} and the common ratio of the arithmetic sequence {BN} are D, and A1 = B1, A4 = B4, A10 = B10 (1, 4, 10 are the number of terms) to find A1 and D

An = a1 + (n-1) DBN = B1 × d ^ (n-1) A1 = B1 A4 = B4 so a1 + 3D = B1 * d ^ 3 (1) A10 = B10 so a1 + 9D = B1 * d ^ 9 (2) subtraction: 6D = B1 (d ^ 3-D ^ 9) A1 = B1 = 6D / (d ^ 3-D ^ 9) substituting (1) or (2) A1 = 2 ^ (1 / 3) d = - 2 ^ (1 / 3)

Connect the pz220v-60w electric lamp L1 and pz220v-100w electric lamp L2 in series and connect them to the 220V lighting circuit. The power consumed is P1 and P2 respectively. If L1 and L2 are connected in series, the power consumed is P1 and P2 respectively
When L2 is connected in parallel, it is connected to the agreed lighting circuit, and the right power of the trumpet is P3 respectively. If P4, then P4 > P3 > P1 > P2 why?

When L1 and L2 are connected in parallel, the power consumed is the rated power of the bulb. When 100W is greater than 60W, P4 is greater than P3
When L1 and L2 are connected in series, the current is equal and the voltage of the divider with higher rated power is smaller, and the voltage of the divider with lower rated power is higher, that is, u2p2
Since the voltages of L1 and L2 are less than 220 V after series connection, P3 > P1
Finally, the conclusion is that P4 > P3 > P1 > P2

Simple calculation of 25.23 * 4-5.23/0.25

=25.23x4-5.23x4
=4x(25.23-5.23)
=4x20
=80

The coil resistance of a DC motor is 4 Ω. When it is connected to a 220 V circuit and operates normally, the output power of the motor is 1 kW. What is the current passing through the motor at this time?

The output power is 1kW, I = P / u = 1000 / 220 = 4.5a

Simple calculation of 7.28 + 3.2 △ 2.5

7.28+3.2÷2.5
= 7.28 + 3.2 x 4 ÷ 10
= 7.28 + 1.28
= 8.56

How does nuclear power come from

Nuclear fission

A practical problem about the fractional equation 150 / x = (150 / 2x) + 2 is worked out,
It's urgent now

It takes two hours more to ride an electric car than a motorcycle 150 kilometers from land a to land B. It is known that the speed of an electric car is half that of a motorcycle
Let x km / h, then 150 / x = 150 / 2x + 2
The solution is x = 37.5
